I think what this last week shows is the amount of effort Malcolm puts in to keep this site clean. While he is away, I am zapping the offensive stuff when I can, but I do a lot of evening meetings and that seems to be when they post. The buildup of new yukky members is also indicative, as he zaps them daily, but I haven't mastered that art yet.
TTwebsite has a fairly high security setting, but when you see what infiltarators did to RRR, which is a paid membership site, it shows how difficult this is to combat.
Incidentally, I get about 200 spam messages a day, which is why I will be changing my email address soon!
They are all so boring aren't they...
