I expect you're aware but just in case... recently (last two or three months maybe?) I've noticed a change in their behaviour, in that previously I'd just randomly find them in my inbox, and now, very frequently it appears within the hour of me logging in. Like it is now watching for people to log in.

Doubt it's helpful to know but it's a new fact.

Incidentally, personally don't find this volume of messages too annoying - I wonder if I have a high tolerance, or, if the other guys asking about it get more messages for some reason.

Personally I am getting tired of the frequent "hello's" in my mail!

You would figure by now they would be able to tell the spammers by now
The names alone are a dead giveaway

This is just something that we have to tolerate. It's really not that big a deal. There's spam in all porn sites. They are never going away. Just delete them.

it would be nice if, when a person is banned for spamming, their e-mails they sent and content they posted would be deleted as well.

The spam emails are posted by bots. They don't post content to the boards.

Most annoying, but I simply delete a Subject like with "Hello".

Somehow they must have success with getting some guys into those sites, they link to.

yes they do, I reported 2 today

I guess they must or why would they bother? Kibd of like the car warranty phone calls, who the hell falls for that?
