https://www.mediawiki.org/wiki/Special:AbuseFilter/28 was not working for the recent spam that Quiddity deleted, and because I know the other conditions of the filter are seemingly not affected by Flow, the problem is likely that the action variable is not the "flow-edit" or other action I expected.
The WMF core features team tracks this bug on Mingle card https://wikimedia.mingle.thoughtworks.com/projects/flow/cards/722, but people from the community are welcome to contribute here and in Gerrit.
added_lines etc are not currently supported. new_wikitext & old_wikitext can be used now. There's a patch in gerrit already to also introduce added_lines: https://gerrit.wikimedia.org/r/#/c/106688/
Change to accurate summary
patch merged, will be deployed to prod jan 30
