We need seventh sandwich on this case!
We know that you're not using a ipod touch.
Seventh would:
A) Look up his email
A1) See if his email has the names of any banned users in it
A2) Cross-reference it with the emails of banned users
B) Find their steam
B1) See if their steam name is that of a banned user
C) Come to the conclusion that he is a friend with nothing to do
THERE IS NO MAGIC TO THIS, SEVENTH IS A friend WITH NOTHING BETTER TO DO THAN HARASS BANNED AND NEW USERS
forget
OFF
