Forum Hello all quick question
 

I have noticed that i get a lot of what seems like bot sign-ups, they sign-up then try and post some erroneous post about an off topic post, but they always have a signature that points to a Viagra site or something like that.
I was wondering are they real people using signatures to spam, or is it a bot system getting past the captcha system that vb uses?

If so is that why people use the better paid captcha system or what. I simply allow them to sign up but i don't allow signatures on a registered class, this forces them to post like 30 times then i dump them into a higher class that does allow the use of signatures.

Any thoughts
