Spam Private Messages .

Why am I getting spam pm's from people on here?
I am getting emails to notify me of these and and it is a touch annoying that they are just spam .

I thought someone here may want to know about this or may know about it already .

I deleted a few but it is the same message from :
bananaguy
viper187
carspeed19
daredevil6
marc0007

all of them have a zero post count and only registered here a couple of days ago.

Although I don't pot on here it would be a shame if I stopped using these forums because of a few spammers.

Thnx!
