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 number of months out of my list. Wish I didn't have to but I do.

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