Massive increase in spam signups/posts lately?
 

Has anyone else experienced this?

Over the last 3 days or so, all 3 of my forums have had a MASSIVE increase in spam user registrations and posts. I have all forums using reCaptcha, as well as question/answer human verification, as well as click link on email to validate. They're still getting by. Right now I have all my forums set to no new registrations.

My one forum, set to moderate new users, was getting 10+ spam registrations per hour. Thank gawd for the Delete All option on moderating new users.

The IPs from the new users seem to be spread out.

Has anyone else noticed a huge increase over the past few days?

Is there an easy way to change the filename of the registration php file so that bots can't automatically load it by it's default name?
