I had to delete about another 25 posts from forumengers that mentioned the spammer, as well as a couple of profile messages on the spammers' profile that repeated all or part of the spam.
Please, never ever quote a spammer, ever.
In fact, don't give them the privilege of having their username/spam message appear in the posts of regular users.
Slag them off, do what you want... just don't actually mention them, as that is helping to preserve their spam in a way that they cannot otherwise achieve.
does this include nursery avoiders? Only reason I ask is I think that having evidence for future possible avoiders is a lesson. Like a hangman on a road intersection before a town. A warning. Or should I just avoid quoting them as well?
