8.1 Use of Lobby kick/ban tools
The kick/ban tools are for use at the Lobby leaders discretion only. Lobby leaders are encouraged to be good hosts, respect other players and use these tools sparingly. Any abuse of these tools will be met with a lengthy ban. Some examples of Abuse of these tools includes things such as kicking all players who join, kicking players as an act of ill will, kicking players because you 'forgot to reserve' a slot, etc...
Contrary to this, it is acceptable for Lobby leaders to kick those players whom are constantly griefing them, or people they associate with.
In addition to abusing Lobby tools, excessively kicking/banning players is not allowed; as a general metric, indiscriminately kicking more than 5 players in one Lobby may be met with a ban.
You actually kicked 4 players. You might want to read actually read up on the rules. Appeal again when you've done that.
