My forum is getting lots and lots of spam lately. -- i've had to close people joining its that bad.
The problem with my forum is, its very customised, and i have to leave guest accounts open aswell, as they can "post comments" on games and stuff.
For the memebers forum, i do have image verification turned on, but im sure the spam is from bots.
What would people reccommend to stop spam?
I would like to start by doing this: Guest comments cannot contain URLS -- i think this would work well, but dont know how to check in php if posts contain urls.
Is there any easy way to write a mod to stop spam? to remove all message from single user, to delete lots of posts in the same thread at the same time?
Thanks so much.
