Lamers joining to troll by AFK

[Kantakwa]

What might work here is not a player vote system to vote other players out, but rather vote and rate the mini. What allows that player to troll is that the other players have no option to just quit and join the next mini without him, because of cowards shame.
So, if for example a mini gets voted down, it would give no cowards shame and less rewards...allowing for players to leave and start another with better chances to not have the troll in it.

No. No no no. You do realize that this would just help trolls to achieve their ultimate goal: Nobody can actually play. Because for the regular player the only way to avoid trolls would be to activly vote for the content he wants to play not to happen. The mini the troll is in would be voted down, but there is nothing that increases the chance that he would not be in the next mini. Which would be voted down, too. Nice, voting down minis in a row is not pvp.
This would be wrong on so many levels I am really surprised you came up with crap like this. Trolls want to destroy the fun other people, so in order to conquer trolls we choose NOT TO PLAY AT ALL???
To make social gameplay fun for the majority you have to remove antisocial players. And not the whole gameplay itself.

You have a point if the troll votes down the mini too and thus becomes indistinguishable from "normal" players. Otherwise you could simply give players remaining in the voted down mini a tag or otherwise make sure the teams are not the same. But basically the suggestion assumed the troll could be tricked...and this means more work for the legit people. As the only measure against said troll it might fail short as you say, yes. It still would be better than an abuseable votekick measure imo.
Best would be more players in minis in general so one troll or (group of players/guilds) can not manipulate or ruin minis as easily as now. Every suggestion here, except explicit gm monitoring and catching the troll in breaking the rules, has flaws...
