I am looking for some advice.
Over the last couple of days my forum has had hundreds of new users sign up and they are not posting all sitting with zero post counts. I searched IPs and they are all coming from the Ukraine and Russia.
I was using the Q&A verification for sign up and changed it to reCAPTCHA but it has not made any difference they are still coming.
I have switched off new registrations and purged about between 300 and 400 and got it back to normal users, but as soon as I open up for registrations again after 10 min they are at it again its really starting to get on my wick.
Any help is greatly appreciated
