After T173889 is implemented and deployed, someone with shell access should query the abuse_filter table on all WMF wiki databases and find all cases were a filter uses a deprecated variable is used (e.g. article_text).
Once that is done, a global sysop can edit the filters to use the correct variable name (e.g. page_title). This task is for the WMF sysadmin request for querying the database to find these (e.g. with sql and foreachwiki maybe?)
