If I were to SPAM these forums...

[StouterTaru]

Let's say I just created 20 new threads, each containing an identical advertising message. SE would act IMMEDIATELY. The threads would be gone, my account would be blocked, and I would never be welcome back. I'd wager it would happen in a matter of minutes.

That isn't what happens to any of the people that spam "<Server> Static looking for <job(s)>" threads that get put into every single server forum until the poster hits their daily limit.

There's at least a few per week.
