remove existing spammer accounts?

[guaka]

approach: use pywikibot to weed out articles based on keywords and structure

• [x] @guaka find existing code to do this not needed
• [x] get some pywikibot code to work not needed

[guaka]

looks like this is not really needed

we could still remove some of the existing spam users @zrthstr?

Actually, I recall that it's problematic to delete users from a MediaWiki installation.

This is interesting: https://superuser.com/questions/600818/how-do-i-delete-all-non-confirmed-users-in-mediawiki

But I think it's not worth our effort, better spend time on #186

(If we are happy with that and some other things, we can come back to this.)
