imo the whole case has several different aspects to be looked at from different point of views :
1) the decision to rollback handled by the admin who didnt backup his own "idea" by talking to others. this is imo the misstake in this case. there is no doubt that one admin alone should never decide deals that are not "TOTALLY obvious" cheatings (examples for obvious ones : unanalysed tryouts for big amounts, shit limits for big amounts, players worth 0 going for several k - sometimes even multiple times from same buyer/seller and so on).
this bid was on the edge, with arguments why u should rollback and why u shouldnt. result : deal needs to discussed internally before acting. u have enough time after the deadline passed.
if i understand it correctly, the responsible admin put his excuse. still, it was a misstake, that would have caused NOTHING (!) if the bid was legit, just put it back on again and if player was worth the price, u will get it again.
2) the question if such deals should be rollbacked in general, that got nothing to do with the initial misstake. it is a more general idea HOW admins should handle deals and the game. there was NEVER a straight line inside the admin team, at least not since i am a playing user. sometimes u saw very similar deals just going through (argument : everyone can bid whatever they like, no matter if the idea to buy this player is totally retarded nonsense and buyer seems to be not active either) and just as often, they were rollbacked.
this ALWAYS caused problems, because this is a big unfairness. we dont need to talk about clear cheatings here, those went through way to often AS WELL, but thats hopefully a matter of past (i am not bothered checking TL for cheat bids like i did in past anymore, cause most reports led to nothing anyway).
one thing is certain : this game needs clear rules, and clear movements accordingly. it is pure shit if deals can be so-so. either rollback cases like this, ALWAYS, or dont do it, NEVER. nothing in between. i am agreeing 100% with zoif here. too many deals alike went through, and suddenly get rollbacked. then go through again and so forth. this is nonsense.
3) last aspect, that in the end has nothing to do with the rest : kick of the player. i dont see a single reason why the player should be given back. it was a complete free will decision, the owner wasnt drunk or drugged (at least i didnt read anything about this), neither "out of his mind" (in a psychological aspect, that would make him not responsible for his actions). in all those situations, a "recreation" of the player would be ok (and rules should be accordingly, if the manager can proove those points and is willing to). in this case, i dont see a single reason for it. IF so, the player should be created to the transferlist, so the game doesnt lose a top player.
4) you guys should stop acting against eachother, com X vs com Y and such shits, the responsible admin stated it has nothing to do with it, you might disagree, but this discussion is nonsense, it leads to nothing, as the true reasons (if others then the stated ones exist) will never be found out. well, maybe in far future if it is possible to sneak into someones head and read minds.
