We have noticed a massive increase in SPAM specially from China.
Users to tend register on our website/forums and just update there profile with a link to some #*$!/pharmacy/buy viagra or similar kind of SPAM site.
We catch more then 200 user-registrations from same IP and/or same IP ranges many times.
We do not do a email verification now on our websites/forums.
We have a manual question/answer system to avoid auto-bots (we are not using re-captcha or any other kind of captcha mechanism)
Is there anything we can do to avoid this kind of fake registrations ?
Are these auto-bots or someone registering on our website ?
