Reported at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#Irrelevant_tags , quoting below: Why would [http://en.wikipedia.org/w/index.php?title=M.R._Organisation_Limited&curid=44080416&diff=629153289&oldid=629153016 this] edit get [[Special:Tags|tagged]] with copyright violation template removed and speedy deletion template removed if the edit did not remove the templates? Is this a bug in the tags system? The user used HHVM and VisualEditor, is this relevant? [[Special:Contributions/109.79.177.119|109.79.177.119]] ([[User talk:109.79.177.119|talk]]) 09:43, 11 October 2014 (UTC) (The page in question has unfortunately been deleted since, but the data is still there, just hidden.) I did some quick investigating: * If you review the page history a bit (which I managed to do before it was deleted), the two templates were indeed removed at a point (and that was correctly tagged) and then restored, with the next edit being tagged incorrectly. * You can examine the logic that led to that edit being tagged at [[Special:AbuseFilter/examine/log/10945503]] – if you look at the row described as "Unified diff of changes made by edit", you can see that AbuseFilter really thinks these tags were removed in that edit (although they were not).

(Adding 'hhvm' keyword just in case it's related to that.)
Here is another example on Portuguese Wikipedia: https://pt.wikipedia.org/wiki/Special:AbuseFilter/examine/log/1898713?uselang=en https://pt.wikipedia.org/w/index.php?diff=40613438&uselang=en The string "{{ESR2|" is in "removed_lines" but not in "added_lines". However, it should not be in the "removed_lines", because it is still in the new revision: https://pt.wikipedia.org/w/index.php?title=Zats_Boy&action=edit&oldid=40613438 This was reported on https://pt.wikipedia.org/wiki/WP:CP?oldid=40613984#Falso_positivo_na_etiqueta
