I always see things online about girls, especially on CoD, getting harassed but I've been playing games for awhile now (started CoD with mw2) and I have yet to receive any crude or harassing messages. I call out locations and participate in any conversation, but I don't single myself as an attention seeker or anything. The most I've ever received was comments like "oh it's a chick" or "do you have a boyfriend?" (which is always just jokingly) but definitely nothing offensive. If anything, people are more supportive when I do well (although I don't need it, I'm not offended and it doesn't feel condescending). I just feel like CoD gets a bad reputation from a handful of bad players, when it's not that bad of a community as a whole.
