This is my stance on the issue with nix.
I don't agree with people belittling you, or calling you a degenerate, or ETC. However, i do believe there is a place and time for this stuff and some of it looks like it's so close to ban material it's ridiculous. If you really wanted to keep finding/using/discussing odd suggestive images, i would recommend either just accepting some people will give you hell for posting it in a public topic and report them if they take it too far; or make a private chat and only let trusted people in.
As for everyone giving him stuff about the images and etc, even if it is odd; if he's not hurting anyone then you should leave him be. If you really are made uncomfortable by one of his images, or breaks a rule, definitely throw a report out on him and end it at that. I'm pretty tired of seeing weird images in typically unrelated topics from nix too.
Btw some of you need to learn the definition of "irony"
