Notes:	Catch copy/paste vandalism like hahahahahahahahahahahahaha. --Wknight94 This doesn't need to be private. -BJ This has far too many false positives to be set to disallow... Not to mention that it seems to block people from using "..." and "'''''" (for bold/italic), amongst other things. --Conti It can at least warn. "'''''''" problem is fixed now. Added curly brace exception too. Need example of "..." since at least 7 occurrences are needed to trigger. --Wknight94 Changed title to something more neutral. --Conti Too many false positives - mostly in reference URLs. Unless someone has a clever way to fix, this is causing more harm than good IMHO. Agreed, please do not enable this filter without substantial changes, and substantial log only testing. -Prodego removing the quote, it was triggered by '''xxxx''' in certain cases -- Luk The filter should ignore urls. - Ruslik Ignoring all edits with URLs in them isn't a good idea. I've made it a bit more complex, actually checking if a link contains repeating chars. If any added link contains added chars, it stops. Theoretically we could do all sorts of counting to make sure there isn't a link with repeating chars AND other repeating chars, but I think that would just eat away at needless conditions, considering it is likely very rare. -Prodego Turning out not to be too useful and the filter is overwrought now. Disabling. -Wknight94 Merged testing edit summary from 292 - Shirik 12 Feb 2010 Optimized summary block - Shirik 12 Feb 2010 ignoring if repeated chars was already there, per request -- Jun 18, Soap Merge filter 366 into this. – Oct 28, EdoDodo Filter tripped the rate limit.

Based on a change suggested by Tamzin. --Suffusion of Yellow 20:00 1 Apr 2022 == for comparison! --TNT Excluding "begin" and "end" (and related valid pseudocode terms, like "endif", "endwhile", and "endfor") to avoid false positives relating to nested begin-end loops inside (pseudo-)code blocks (see: [[Special:AbuseLog/35527217]] and [[Special:Diff/1165729932]]) -- RTH 16 July 2023
