Don't give me random invites for groups or to be "friends"

No, I don't want your cents worth of weapon skins.
I know, a "steam admin" wants to "check my items" because they're "duplicated" and apparently, "they're against the rules"
No, I don't want to be friends with a stranger I do not know.
And no, I don't want to join a group about something I don't care or that I find fishy.
