yes, and of course my first order of business was
DROP FROM
steam_friends WHERE
steam_friend_ID IN (
SELECT sf1.steam_friend_ID FROM
steam_friends sf1,
steam_groups sg1,
steam_friend_groups sfg1
WHERE
sf1.steam_friend_ID = sfg1.steam_friend_ID AND
sfg1.steam_group_ID = sg1.steam_group_ID AND
UPPER(sg1.steam_group_name) like '%DARKLY%' );
