First off you can't be offended if you don't even know TO be offended. If I was walking around wal-mart and some perv was using X-ray specs on me without my consent...A) how would I know, and B) why would I care? I can't be offended or embarrassed unless I know TO be embarrassed or offended. Same here, unless they sent me a live stream of my character in the buff I wouldn't ever know they have the mods up, and even if they told me the rest of the party probably doesn't have them up so the easiest solution is to boot the perv and move on.
As for judging by people's typing or outfit, maybe some do. Probably most don't though, and getting upset at someone's outfit is like an RP player getting mad at all the 'not actual names' people name their characters with. I gave my character an actual name, and I dress in what I feel is an actual outfit rather then tank in the buff or run around in a chocobo suit. That is my aesthetic, and if you have a problem with a 'mystic cowgirl' themed magic user...oh well. Yes it may impact 'your social space' but at the same time it's a personality thing, and frankly that kind of is the point of playing these games to begin with.
