Rarity and Dank have been going at it for ages. If Rarity was officially banned for that it just seems like an excuse. Besides, if anyone was trolling there it was the guy who intentionally played a poor version of Mary Had A Little Lamb just to get a rise out of her.
So you are a new user, but you have actually watched Pony and Dank going at it for ages? But I digress, you don't get banned for calling out the mods, I've seen people do so on various occasions, and I've seen them get pretty vile while at it. If Theymos or any of the other mods just took their liberties at banning, this forum would be a lot emptier place, as there's a new thread about one of them being a bad mod, or being incompetent, or just an asshole every day. They don't seem to care that much.
My point is, if you get banned from here, there's probably a real reason, as I haven't ever managed to get banned, and I tend to have that tendency.
