Steam needs to make it so that only people with leveled up profiles can make groups.

Each day I get spammed with around 3-5 CSGO trade scam groups by a bunch of bots with 1 hour in MW2. This problem could easily be fixed by either restricting community group creation to those above level 10 or simply allowing users to block out all group invites from non-friends, rather than force others to make their profiles private.
