the arbcom.de has recurring cases, where there are two conflicting user groups. Their conflict usually has become somewhat personal over the years. Both groups gang up on each other leaving provocative remarks in a matter of minutes. The conflict usually also has been occupying our admins for years, has driven away some productive authors from the german language wikipedia and it prevents third party editors from improving the disputed page(s), as they normally try to not get involved in the conflict.
For this reason, we're opening this phabricator task to create the variable 'ARTICLE_LASTXH_CONTRIBUTORS' for the edit filter (aka abuse filter). With this variable, users (or user groups) could be defined, who cannot edit an article or discussion page for x hours after the other user (or user group) has edited it and vice versa. In effect, this would be used for a user (or user group) separation filter. This temporary mutual exclusion filter would leave both users (or user groups) some time to reflect, it would slow the escalation rate, probably permit third party editors to edit the article, and it would reduce the work load for the local administrators. Most importantly, it would also be a less invasive measure compared to a user block. The filter option could be combined with bans imposed by an arbcom or administrators as an additional tool.
If it helps, x could be any numeric value, but x could as well be limited to the 4 values 2h, 12h, 48h, or 168h.
Thank you very much and kind regards, ghilt
