they are spammers my friend.
B.O.A. stands for Banned On Arrival, and then there is a date and time of their "failed" registration attempt, they are 90% from russian extraction and 10% chinese. What happens is I can't delete them otherwise they will try again with a different name so, what I am having to do is ban their IP address and fake email address so next time they try they can't get in. If I just deleted them straight off as I used to do at the beginning 4 years ago, they'll keep coming back. So now they are finding it harder and harder to register.
Their registration is often linked to a website advertising fake nike shoes, rolex watches, viagra and all that kind of knock off sh|te.
I am at war with them and since day one of this forum never one of those ####ers managed to get through my iron curtains
