No. There's something creepy about a culture which seems to believe you should only befriend people your own age, and that anything more than 15% either way makes you a pervert.
I do think, however, that you need to be careful what you say. I remember playing Half Life online about 8 years ago, and I caught myself using the same profanities I would use amongst friends at our weekly LAN party. What might be a perfectly innocent profanity to me ;) might raise a few questions if other players were particularly young, and I had no way to know, so I reigned it in a bit. Social networks could easily lead to similar misunderstandings.
