What do you mean? You have to accept a friend request before someone can message you. It's more spam-resistant than email, not less. That said, I don't know if there's anything that prevents spamming friend requests.

And how am I going to find the valid friend requests under the hundreds of spam ones? I used it just like a chat version of public email, for bug reports and such, so I don't know who is going to message me beforehand.
