Hi!
I am really sorry to disagree, but the thing you did with Armok was not as harmless as you may think - unless Armok himself declared his avatar fair game.
Basically, as ThreeToe pointed out, you picked one member of the community and made fun of them - in Japanese schools, you call that "ijime", in Europe and the US, you may have heard of "bullying" or "mobbing". And before you say "It was just some nice fun!" - that seems to be the sentiment behind some bullying/ijime as well. While you do have really nasty cases that are really out to get the person, in other cases, it seems that it is not meant to be mean. But whether it is good-natured or not is something only the victim can decide. And if the victim is not happy about that, you can't call them a baby or anything.
Ijime can put a lot of pressure on a person, leading to various health problems and even suicide. And even seemingly harmless rites can build up to extremes.
I have to admit that I didn't know what to do when I saw you do it. I was afraid of starting a flame war about this and hoped for it to die down. I am aware that that is the big mistake people often commit when dealing with this (adding a painful experience to my book), and I have no excuse for that. And before there are any misunderstandings - I did not call the moderators on you.
