I've deleted the latest spam, but although it's one of those automated things, without banning the user more stuff will keep appearing (as has been the case), so I've popped an e-mail to Ste as only Admins can do that.
Just thought I'd post this as people ask for the stuff to be removed, but I can't reply to those directly because the whole thread is deleted in each instance!
I went to the old The Cakes forum recently, and wasn't surprised to see some spam. What did surprise me was the spammers had been kind enough to confine the spam to just one thread that contained nothing but spam. How civil of those spambots.
What considerate spammers!
I've deleted some too - it seems to come in waves, but luckily small waves.
