Hello. As of late my wiki (nonciclopedia.org) is being targeted by spammers, likely robots or such, who create new accounts and after a few days of basic edits in their user page they start adding redirects to a spam page in hundred of already existing content pages. It's a major pain in the neck because I can oly rollback them one by one.
All I need is an Abuse Filter useful to stop behaviors like that without distrupting the experience of new users, but I have only a basic understanding of that extension. Could someone give me an hand?
