I have been unfairly banned

This afternoon I entered an RDF dungeon, and there was a DPS paladin with the role of tank with shadowmourne and we told him to change to a tank.
A back BoE ilvl200 was dropped and I asked to give it to need to send it to my druid if it did not matter and nobody cared, the paladin said nothing, but right after he said that he had reported me by ninja in the dungeon, I have tried to connect and I cannot .
I do not know if I will have more reports for that or something, but I think I have never done anything like that and a report is enough for them.

If you we're banend it would tell you that, your connection issue is probably something else.

That said, rolling for something that isn't your current spec can get you reported and banned.
