I don't take friend requests from strangers or private profiles. Unless I know you from somewhere, leave a comment on my profile on how you found me if you want me to be friends with you. You can also leave comments on my screenshots or guides or just about anything I've created and uploaded on Steam, if that's your thing.

Also, unless I happen to have met you in meatspace, and/or have friended me on the Backloggery, hands off on my inventory. That goes for both TF2 and Steam items. If the first thing that happens after you and I become friends is begging for cards/items and I already haven't known you from outside Steam, you're getting kicked off my friends list.
