Didnt win against cleanupcrew you gave away our position and teamed with other players. Kaine Clearly states that this not allowed:
3. No player interference. If a player in the match asks to team with a clan the clan members must say ‘no’ and treat him as an ordinary player. Friends of clan members must also be treated as ordinary players. Accepting gear which is shared from players or teaming with other players who aren’t participating in the battle will result in a forfeit. Under no circumstances are extra clan members allowed to be in the same game as the people in the battle. If a member of a clan which is not supposed to be participating in the battle joins the server they must leave.
4. No spectators who have been participating in the clan battle. If the owners feel as though they can trust one another to spec the matches then this is fine, however if one clan declines this option then the members must leave as soon as they are killed. If spectators are found giving away positions and details (this includes friends of clan members) a forfeit will be applied. If anyone is sponsored during the game by friends or clan members this could also result in a disqualification. The disqualification will occur of the item is to be used by any members of the clan. If five arrows are sponsored it is expected that they should be dropped.
