EditFilter Idea I originally posted this to Triplestop but he suggested I ask you I ve been looking at the edit filter documentation and I would like to contribute a possible candidate to look for new editors changing birthdates a fairly common and sneaky problem I m not looking for full edit filter rights but I would like to help develop the appropriate filter If you don t have the time to deal with this right now let me know and I ll engage someone else I am new to the syntax but here s my general format right now user editcount 50 article namespace 0 lcase added lines rlike dateofbirth birth da te y born b lcase added lines rlike lcase removed lines rlike Where I have is the birthday searching regex I ve been working on Below is what I ve developed so far I haven t tested it extensively but I ve thrown it against a few BLPs and it works fairly well It finds the usual ways that birthdays are presented either in template or in lead for example b January 1 2010 Here s the regex date of birth b dash born birth da te y 0 3 0 9 jan feb mar apr may jun jul aug sep oct nov dec 0 9 0123 0 9 12 0 9 3 birth I don t know how to check for what specifically was edited as in if a numerical value was changed Is Edit Filter able to do this sort of thing I welcome any other ideas you have I assume this will require more work But please let me know how to push this along
