Filter parameters

Filter ID:	890
Description: (publicly viewable)
Statistics:	Of the last 76,406 actions, this filter has matched 29 (0.04%). On average, its run time is 0.1 ms, and it consumes 1.3 conditions of the condition limit.
Conditions: (documentation)	lcase(accountname) rlike "[bcdfghjklmnpqrstvwxz]{9}" & !('override-antispoof' in user_rights) & (' ' in new_wikitext) lcase(accountname) rlike "[bcdfghjklmnpqrstvwxz]{9}" & !('override-antispoof' in user_rights) & (' ' in new_wikitext)
Notes:	Exploratory filter; looks for new accounts containing strings with NINE consecutive consonants. Just intended for logging at the moment, to see how common these names are, and to what extent it is a good detector of bad usernames. So far, it's looking pretty good, even at 8 characters. Upgrading threshold to 9 to make it even more selective.-- The Anome, 12 May 2018 More investigation: now looks at only first edits for these accounts. -- The Anome, 18 May 2018 Performance improvements -- checking user_editcount will cancel out more actions in this case, so it should come first; similarly reordering other conditions to cancel out more actions; user_editcount < 2 will also be true for blank or false values, so removing !user_editcount to save a condition, and using contains_any for checking multiple actions to save a condition ~MA Removed all the filtering on event type and edit count. This is fascinating: the lack of output from the previous suggests that people are creating these random-typing accounts, but never using them... -- The Anome, 19 May 2018 Adding a dependency on wikitext, to see if that lets this filter see edits.
