Feel free to correct me if I'm wrong, but this is not a big deal for us men. At worst we'd end up with a handful of these misdirected messages and suggestions whereas some of the girls I've talked to seem to get just about as many over the course of a few minutes.
This doesn't really change the fact that there's not a whole lot to do about it without adding restrictions that might scare people away from here entirely. There are too many ignorant and rude people in this world, I'm here for a chance to meet the rest of you.
