Notes:	Manually exclude `DannyS712 bot`, will be updating [[Wikivoyage:Graffiti wall]] with `{{subst:User:DannyS712 bot/reset}}`, see [[Wikivoyage:Script nominations]] --DannyS712 6 November 2020 A noticed a few false positives or nearly so, about users undoing their own edits. One user had tried to add an inline image to a listing and tried to revert when it didn't work, another tried to undo some of their own vandalism on the graffiti wall. The latter may have been malicious, the edit was later hidden. Anyway, not being able to undo own edits seems problematic. I don't know whether the advice to contact an administrator is enough, it is a scary option for many newcomers, and slow. -- LPfi 4 July 2024 adding " &!'autopatrolled\|patroller' in user_groups" after a false positive –SHB2000 7 July 2024 Regarding [[Special:Permalink/4945237#Filter problem]]: We should probably add code for recognising some key part of the raw city/whatever templates and allow the edit in cases where it was present in the old version. –LPfi 26 Sep 2024 Done: I copied some phrases from one city article template (probably some are identical in others) that seem unlikely to be found in proper articles, and hope that some of those are removed in the offending edit, which in that case is allowed. –LPfi 26 Sep 2024 Tried to lessen false positives (also some tweaks and added comments): * Allow if the user is the creator and a recent contributor - the former is perhaps too strict a requirement * Allow revert with default summary mentioning the user - is it possible to get a variable included as part of a match pattern? * Perhaps allow edits removing (also) long strings in non-Western scripts - commented out as for now, needs review and syntax correction –LPfi 24 Oct 2024 I found one more try at self-reverting mistakenly saved translation. I now enacted the check for removal of long strings of foreign chars (or odd ones, excess whitespace etc.). –LPfi 3 Nov 2024 Some changes by SHB2000 today were suggested by Codename Noreste in Special:Permalink/5038134#Suggested_changes_to_abuse_filter_36 (Wikivoyage_talk:Abuse_filters).
