I also was in taint for a couple of years and they are nothing to be afraid of....
They were so large that they were in fact many guilds in one and thus had many many raid teams. They also had their own addons for chat across multiple taint guilds(too large for one guild), and in game member pictures. They were also well know for their Xrated members pics forums section.
The guild leadership took a very moderate approach to discipline and as such guild chat was very explicit which some enjoyed and some didnt.
As always with anything, people always have the choice to be part of it or NOT be part of it.
It did seem that a lot of their members were in the guild more for companionship than the game.
Personally, for this game I prefer a smaller guild than Taint and a focus on game content in an enjoyable and social manner( think i said that right)
Lastly
Its easier to not go looking for drama...
