    Looking at the sheer volume of reports on Google I doubt it is anything but a BOT system , there would need to be 100's of people finding forums and typing manually to hit like this.

    Yes I have email verification on and so far they have not gone beyond the members list as I check the registrations at least twice a day and then delete anything obvious.

    In v3.6.8 I had the DOB requirement, the image captcha, NO SPam and ISBOT running.

    In v3.7 I had the DOB,Recaptcha and ISBOT mod (which still catches 100's a week.)

    Now this bot is adding a DOB, running slowly enough to avoid the ISBOT mod and is reading or bypassing the Recaptcha.

    I have also had it sign up as member " vBulletinBoy " which just rubs it in a bit further.

    I have now switched to the question type verification and will see what that does.

    Anyway I have disabled new registrations on mine as I cannot give this my full attention today, and I'm worried that the spambot goes into overdrive!
    any help greatly appreciated (I'm on a shared server so probably limited options)


    (3.7, not using recaptcha, but the previous image verification)

    Got these two on my forum as well, registering within 2 hours of each other yesterday... Banned their accounts immediately after I saw this thread...

    I am using reCaptcha, with email verification and even two required custom fields during registration... it's not just reCaptcha they're beating, it seems...

    Same for me... email verification and Image verification are active, but they have been able to register and post on my forum.

    I've had the first one and some variations. Clever program - it appears to be reading the form field names on the registration form and submitting appropriately. Most robots don't seem to do that. Made me think it might be human.

    Rotating about different IPs across China, always using gmail.com email addresses, but seems to wait a bit before posting so I've been banning it before it gets the chance.

    I have had these two as well, checked Google and looks like they have registered on at least 1,500 forums in the last 48 hours. I have email verification and Image verification active.

    (and that 1,500 forums are the ones Google bothers to index on a daily basis, real number of infected forums must be vast)

    started a topic Spam bots defeat Recaptcha.

    Spam bots defeat Recaptcha.

    I have the Recaptcha system set up and also use the ISBot mod, in the last week I have had 14 spam bots seed the forum member list.

    these are the last 2 :

    A quick Google shows them as very prolific spammers,this is no manual entry campaign.

    Prior to v 3.7 I used the NO SPAM mod combined with ISBot and never had a single spammer succeed in joining the forum.
