• Editor interaction utility

General:

1. As noted on SPI talk, I am unable to make the editor interaction utility above work; perhaps I am using it incorrectly, but it does not produce any of the interaction noted below in evidence.
2. Further detail at: Wikipedia:Long-term abuse/Mattisse
3. I present here only a very small part of the evidence available; with long-time, repeat disruptive sockmasters, it is not optimal to detail all of the known behaviors. The profile is already known to the arbs and documented at the long-term abuse page; if CUs need more evidence, it can be provided.
4. IMO, the evidence (and my years-long experience with Mattisse socks) indicates conclusively that EChastain (EC) is Mattisse, but to the potential argument that EC can be blocked per DUCK without a CU, I note that there is a current arbcase (in which, btw, EC is stirring the pot, samples [1] [2] [3], there is more) and several previous SPIs along with commentary on various talk pages where the identity of more than one other editor is confused with EC (@TParis:, @Anthonyhcole:, @Drmies:). A CU will be helpful for those other situations and so the current arbcase can proceed without confusion of sockmaster identities. I am also concerned that there has been a recent alteration in normal editing patterns, so that there may be multiple socks to be discovered in the drawer.

Many of these are obscure articles in Mattisse's areas of interest. Examining the edits within these articles reveals the pattern of edits described at Wikipedia:Long-term abuse/Mattisse (for example, tagging at Selective perception [4] [5]) EC has also edited in the listed areas of interest detailed on the LTA page for Mattisse socks. As but a few samples, her first edit was in geology [6], within a month at India [7] and also [8], and not long before she was at psych articles and medicine [9] [10], and Venezuela [11].

Timing

Parabolooidal (talk · contribs · logs) was CU-blocked in September 2014.

EChastain (talk · contribs · logs) was created in October 2014.

Sample behaviors (small number of samples only, not comprehensive in the least, additional evidence can be supplied on request)

1. See user page relative to past profile (noting, btw, that having a PhD in psychology and being an alumni of UC Berkeley is not the same as having a PhD from UC Berkeley).
2. "Poor me", "so confused" and "so afraid" [12] [13] [14]
3. By her 11th edit she was at ArbCom [15], and in other discussions reveals reasoning that supports her switch to supporting her former "plague list". [16] That EC has cozied up to the former "plague list" (Bishonen, Montanabw, and other FA regulars for example) is entirely consistent with the profile and the oft-expressed view of what she considered a "FAC clique" or "incrowd" that she longed to be part of; she seems to indicate that now GGTF is a greater evil than this "in crowd", and opposing GGTF provides a vehicle for acceptance. [17]

Samples of disruption

In addition to the pot stirring surrounding various other arb cases:

Like Mattisse, at the least and most trivial challenge to her authority, (sample of past documented debacles at GA for example) EC switches from constructive and collaborative editing to tag-bombing and accusatory mode: [18] [19] [20] [21] Like Mattisse, EC is capable of decent content work, but that work deteriorates when she is challenged.

A classic example of this is seen at Open defecation, where a minor disagreement over citations in the lead (both parties were partially right and both were partially wrong), leads to the "I am picking up my marbles and going home" behavior, with accusations of article ownership and article tagging. EC was constructively editing until she had a trivial disagreement with EvM-Susana. [22] When she is challenged, she responds with classic Mattisse behavior, and her previous constructive editing switches to tag-bombing.

Like Mattisse, EC involves herself in DR in ways that furthers rather than helps resolve issues, because she not infrequently does not understand the issues. [23] Flyer22 can speak more to that incident.

Other behaviors documented by TParis at Wikipedia:Sockpuppet investigations/Sue Rangell/Archive

I have now taken the time to examine Sue Rangell's editing history, and I cannot find any evidence that Mattisse and Rangell operate the same accounts, and plenty of evidence that they are not the same editor. But Sue Rangell and accounts operated by Mattisse do have significant article overlap, not all of which can be explained by the similarity in their professions.[24] To explain the (realistic) concern that Lightbreather raised about EChastain's first edit being to Mogollon Rim, I think that a good case could be made here for WP:MEAT (some of Sue Rangell's first edits indicate the possibility that Mattisse and Rangell could be acquainted-- if not IRL, then via email). Arbs and CUs familiar with Mattisse geographical areas of interest will find those connections by looking at Rangell's first week of editing. If that is the case, that EChastain has gone after Lightbreather in similar ways to hounding under other accounts could be a factor in the arbcase. SandyGeorgia (Talk) 13:28, 10 May 2015 (UTC)

Blocking repeat sockmasters

Should a CU indicate that EChastain is Mattisse, I am indifferent as to whether she should be blocked. Since Mattisse just registers a new account and keeps doing the same thing, it might be easier if she is left to edit under a known account, where others can keep an eye on her, and she can be asked to refrain from stirring the pot. On the other hand, if she is blocked, her reincarnations are not usually difficult to spot. SandyGeorgia (Talk) 19:12, 7 May 2015 (UTC)

Depending on the outcome of this SPI, Mattisse might request re-opening Wikipedia:Arbitration/Requests/Case/Mattisse to evaluate whether she should be allowed to continue editing under one account. SandyGeorgia (Talk) 13:47, 10 May 2015 (UTC)

• I am quite familiar with the history of Mattisse's behavior and I agree with the conclusion that EChastain is a Mattisse sock. The substantial overlap in editing interests, rhetorical style, and reaction to conflict is clear. I have actually been aware of this connection for quite some time—as Sandy pointed out, her "tells" are obvious and pronounced once you get to know her style. I was ignoring the situation in hopes the she would find a quiet corner to edit in and just be at peace. However, she has shown (again) that she cannot resist slipping back into the conflict/poor me/lashing out pattern that has gotten her blocked repeatedly under various accounts. I am not calling for the EChastain account to be blocked, nor am I convinced that would be the most helpful outcome. I believe she will continue to create alternate accounts ad infinitum, and I believe it might be better if everyone knows what account she is using. --Laser brain (talk) 22:23, 7 May 2015 (UTC)

• Well done, SandyGeorgia. Editors knew that EChastain was a WP:Sockpuppet or some other type of returning editor. And after my unpleasant run-ins with him or her as EChastain, as seen here and here, it makes me want to remove the barnstar I got from him or her when he or she was MathewTownsend.

• The account is technically very  Likely to past accounts. The behavioral evidence is compelling as well. I have blocked and tagged the account. Mike V • Talk 00:21, 11 May 2015 (UTC)
