We've been lucky on the AMS forum, only one spam attempt since I set the forum up, and that was swiftly dealt with by the forum software.
We have our own resident anti virus software....know to all model submariners as 'ALF'. Six foot six, no teeth and speaks his own language....some say he is the legitimate son of The Stig.
All we know is that no spammer would ever dare tangle with the mighty ALF.
