Fujiwara and Meganova need to be warned, yes. Despite how one feels about the current topic, insulting others, name-calling, and general indecency should not be tolerated, and they should each receive a moderate warning each from what I've seen.
As for Malomtek, in response to Every's question, yes. This is absolutely grounds for a ban after I gave him one, ONE, final warning. And with everything I looked up, the comments in the Touhou thread, the message wall comments, and the further comments here, I agree to a one-month ban as DDM has proposed. I feel that Malomtek is not trying to be insulting to others, nor is he intending to start any hostility with anyone. What he needs, however, is to learn some tact. Nothing gets better if you act hostile to a hostile comment. Two wrongs don't make a right. I feel that the best way for him to figure this out is to take a forced break from the wiki, evaluate himself on how he communicates with others, particularly when under fire, and once his ban is over, he might be able to come back with a more civilized approach to debating. I hate to bring up anything regarding a religious context, but Jesus Christ would be a good example to follow in this case, as you should learn to "turn the other cheek," especially during this climate of internet expression that we find ourselves in these days. Please don't cancel me for this closing statement folks, I'm begging you.
