You see a noob and you get pissed off at him because he is doing something noobish. You post negative comments and everyone does the same. He is pissed off because you are acting noobish by posting a negative comment in a clan discussion. Clan fails, you're not satisfied, and the guy is pissed because he can never start a clan. You go to another clan topic and post negative about it. You ending up pissing off a whole bunch of noobs by your childish actions. When you post something, those noobs remember what you had said, then post negative back at you. Never ending circle of hatred towards noobs. So, how about we just don't post negative comments in the Clan Discussion? Sure, he'll bumb his thread a few times, you'll have to see it, but eventually he'll give up. If he is gaining members, then it won't be a "fail" clan anymore. If you look at it, notice how most clans fail when the first comments are "FAIL." If you can't resist making a comment in clan topic, at least give some things the leader could work on to make it better.
Another note, if someone did something stupid, like post in the wrong section, "WRONG SECTION" only needs to be said once or twice. By more people posting causes the topic to bump, and more people see it, and it becomes the a !!! topic, which are read by even more people. Try just laughing at the person at your computer, then change topics. It is very easy to resist temptation of destroying another person's ego, you just have to pause and view how it would affect you if someone posted the same thing to you.
Please, I would request that people not post in Clan topics if you are not applying, thinking about applying, or if you are in the clan.
