Same here. I don't accept friend requests unless I know who the person is for sure already from either past conversations with them in the forums or messages, or I recognize them in some other manner. I often leave friend requests pile up for a day/week anyway, and then go through them all trying to figure out who I know and who I don't know. If I have a request that is from someone I don't recognize off the top of my head, and they have not sent me a message also to let me know why they are adding me or initiate some form of communication to strongly suggest to me that they are legit and not a problem to be concerned about, then they'll sit in the queue as an ultra-low priority until I feel like spending the time to search the forums and Google to try to figure out if I actually might know them or they might be friendly and worthy of accepting the request.

Unknowns need to pass a Google search test as to whether or not I think they might be some kind of scam artist or other Internet lowlife if I don't have any clue who they are going in, and naturally that isn't going to be a high priority, so when people send friend requests they should always state in a private message or in the forums or some other channel of communication who they are and why they added you, or some kind of conversation to indicate they're not a bot, scammer or toxic waste of the Internet.

I've got one person in my queue right now that I have no idea who they are, there is no forum activity from them at all, and a Google search of their name yields a single web page on a Russian forum site which has broken English postings, and one of the other people's avatars present on the page is the same avatar as another GOG user uses whom is not particularly a stellar member of the community here (but that is possibly a pure coincidence). Needless to say, my "no thanks" alarm is going off on that one.
