If you want to add me and we haven't played together, leave a comment explaining why, otherwise I ignore invites by default. I don't have the room to be adding randoms I have no memory of.

If you get removed from my friends list, don't take it personally. My list is regularly full and prohibits others from adding me when it reaches max friends, so I cycle people I can't recall or haven't spoken to in a long time out of my list. Wish I didn't have to but I do.
