Well is not about that... But we don't have organization or /care about votes from members to invite new clannies!
On my clan (Flame some of you may know them from L2TheGame) we had only 5 voters: 4 Core memers from clan the leader! so if you get 3 vote from 5 you get recruited if not you dont no matter who did -1 or +1, we had test period to acomodate with the recruit and test his skills and so on! but I guess here is quite hard to do the same or w/e. even if we vote as we vote like now I don't think is fair that if you get +10 votes and -3 votes to get rejected... Nobody want to leave clan or to see another friend that do this thing cuz x/y/z got recruited, but all should get a chance to try play in this clan
