| After yet more run-time, this seems to be doing well at catching LTA/potentially disruptive usernames, with no false positives so far. I think we can probably leave this to run indefinitely without any further problems. -- The Anome | | After yet more run-time, this seems to be doing well at catching LTA/potentially disruptive usernames, with no false positives so far.

| Re discussion on [[Wikipedia talk:Edit filter]], now triggers on four repetitions of four, or five repetitions of three, OR five _successive_ repetitions of a character pair (10 characters of repetition), thus detecting, for example, "aaaaaaaaaa" or "ababababab". It also now uses [[MediaWiki:Abusefilter-disallowed-repetitious-username]] as warning message. -- The Anome, 3 April 2018 | | Re discussion on [[Wikipedia talk:Edit filter]], now triggers on four repetitions of four, or five repetitions of three, OR five _successive_ repetitions of a character pair (10 characters of repetition), thus detecting, for example, "aaaaaaaaaa" or "ababababab".

| Getting very slightly more aggressive by also adding four _successive_ repetitions of a character triple, (12 characters of repetition, eg. "blablablabla") and three _successive_ repetitions of four (12 characters of repetition, eg "asdfasdfasdf") This should catch more valid cases, but I believe should not catch any of the false positives discussed earlier. -- The Anome, 8 May 2018 | | Getting very slightly more aggressive by also adding four _successive_ repetitions of a character triple, (12 characters of repetition, eg.
