any team with cloudmaker on it
any sandbag team ever
that team my noodle is moist that went undefeated in open until someone realized it was mgib and a bunch of IM/invite players alting while also playing in their respective divisions
my open team who's name consisted of the letter d repeated the maximum number of times allowed by esea
that team with tictack and spaceghostpurp that went undefeated in IM and died in playoffs (sgp had a similar effect to cloudmaker in making people hate his team simply because of how big of a shitlord he was)
p sure whichever season main was a thing there was a team with like blaze and youmustmike that brought in clockwork and a bunch of invite players to win the div in playoffs and nobody really liked them i wouldn't say they come close to the most hated in history though
