If you go back and read the thread you're referring to carefully, he was *blaming* the fact that he had a bad experience on that server on the tekkit devs and anyone involved in this website. He was acting like he wanted the them to do something about the fact that he had a bad experience on that specific server.
Initially people tried explaining that those servers were not the tekkit dev's responsibility. A normal person would have said "Oh, I didn't realize that, what can I do about it then?" And the conversation would have moved on and been productive from there.
The issue is, the guy was an idiot. Instead of realizing he was being an idiot, he continued pressing and forcing his point and not actually making any positive progress in the thread because he was too determined to prove that everyone on this forum was wrong, and he was right. You can't help those people. It isn't a possibility. I guarantee if you had posted your advice in that thread he would have ignored it and continued ranting on about how the tekkit devs are terrible people and someone owes him his donations back.
Also, the fact that we're even having this discussion and you weren't just banned is an immediate indication that your argument is invalid because you're not giving us our laughs. Try not to make your assumptions of an entire community based on one single thread.
