I guess so. Though, it wouldn't phase me much. The "drama" I've dealt with online, the games that have been played, all throughout the years of being online. Someone pretending to be the opposite gender, is sorta small on the list.
Dont really care, not hurting me and it's all harmless fun. just some nasty chat and jerk
Depends on how deep the lie goes. If it is just being silly than whatever but if it is a serious breech of trust then it could be a problem.

Ask Manti Te'o.
I wouldn't be happy, but then I hate being lied to.
