people on this site do not follow the rules - the rules are there to give admins the OPTION of punishing someone. But many times, a user is flamed and flamed and flamed, even when they're activity on wiki is constructive and well-intentioned.
When that user tries to justify himself - or try to point out the un-productivity of flaming - he is flamed more.
This is immaturity - something common in young children but rampant on these websites. It breaks multiple rules that can be found in PvXwiki:Policy, but is generally ignored by the admins.
Most mature intelligent people forget about interacting with other people on the site at this point - which further hinders the growth and development of the site.
People who actually want to participate in the wiki, and who post things that are different from what people are used to seeing are actively and maliciously flamed, without consequence from the admins.
Let me ask you, can you see where this will lead? If not, i can tell you that if this person does not leave the site, then he will eventually react in kind. A good, kind-hearted person might hold out longer than others, politely asking for respect, trying to point out it's stupidity, but the people who do that rarely if ever listen to such arguments, and it usually furthers their enjoyment, getting a taste for torture, as it were.
