Rules:
I will not accept your invite, if your profile/inventory is private.
Don't beg me for free keys/items
Don't spam me with game/group invites. You will get a free block and remove.
Don't try to scam me with real money tricks, you'll waste your time.
If you'll have me at pending friend requests, please write me the reason of adding in comment section, so I know what you want.

Basically, those are my rules, no big deal. Try to be polite and have fun!
