Trolling

A few weeks ago, I made a friendly thread entiltled "gnomes" saying "Yes, I am a gnome, what of it?"

The idea was just to have a laugh about gnomes and the way some people genuinely seem to hate them (even though its PIXELS).

I got a 2 week ban for trolling...

After looking at the rules more thoroughly I could understand it, I didn't agree but I could understand.

Now however every thread I read or make has at least one troll making a completely useless post or flaming response, and nothing happens to these people...

Is it accepted now or what???
