@Calgon, even if this will work, they're still amount of +-200 different players with different names. Even if they connecting as xx_Clan_xx which the "_Clan_" stays the same in every name, they can easily change it to random player names, or increase the amount of IPs to higher then 500.
The solution could be any way to find the difference between faked player and real player. Currently, I can think about one idea - captcha - but this will still have the players in the server, lagging it, and taking slots.
