DK,
 I think your confussing things,a mass report is just that multiple players reporting an offence.
 Several players whether in 1 squad or many using foul language is not the issue!
 I would think the player or players involved in foul language would be dealt with on a per player basis.
Where as the mass report,if done maliciously to have another player muted,would and should be dealt with differently.
 I totally agree with Shuf and others on this matter,if a squad is found at fault they should be dealt with as a whole and if this happens to affect you maybe you should rethink you involvement with such a group.
