Based on the screenshots posted here, all I see happening is taintly and AndrewJR agreeing on a deal in TheOne's game. There's nothing wrong with that.

AndrewJR posted in his first post what his side of the story is, and he admitted to being a bit BM, but if what he says is true then he was actually looking out taintly's best interest, and TheOne was trying to rip off a new member and ended up losing the trade because of it.

TheOne, if you have proof of taintly accepting your offer of anni + 8hr then you might have a case, but even then I doubt you'd get the armor back unless taintly and AndrewJR both agreed to trade back.
