I'd have to disagree with you a bit there.
Firstly, I guess I forgot to mention that the type of game that I play is geared towards prepubescent-mid adolescents. So yes, they do accuse me of being a "46 yr old man" just because I speak coherently and with no frills.
Secondly, even if they weren't immature kids, people do still make judgements on you based on the way you express yourself on the internet. I'm sure you're guilty of it yourself before. if i wer too suddenley start tiping lyk dis, or start talkin' like bitch yo', you would immediately make assumptions about me, my age, my gender, my education etc.
Thirdly, there are many desperate/horny guys on the internet, that will do anything for you if they know you're available. Whether they are genuine or "testing" is irrelevant. Either way, they still change their attitude towards you.
Finally, don't get me wrong, I'd be the last person on the internet worrying about what other people thought of me. I said that I'd rather play the game, and "be one of the guys", than to have "special treatment" just cos I'm a girl.
