I just cleaned up 12 new spam pages. I think it might be time for a less scriptable captcha.
I know if won't stop some human from manually doing it, but maybe it'll slow them down enough.
Admittedly,I have dropped the ball lately because of life (health and time issues). I used to check edits almost daily and remove spam and associated accounts, but I kinda stopped after the end of summer.
I'll get on it, and see what more I can do to prevent it. Thanks for reporting!
