I appreciate your efford but don't quite agree with you, OP, to declare most of it as spam. That doesn't really help in my opinion. As BlackBoss_ highlights, a lot of your categories are covered by one or another forum rule and if you spot blatant violations against forum rules, feel free to report it to moderators.

Spammers spam because they have some sort of incentive, whatever it is. It's a fight against windmills...

If particular users annoy you, simply put them on your ignore list. Silence is bliss. Mostly...
