BitcoinDistributor is also moriartybitcoin
You edited this to include the quickseller part for some reason.....
You have a shocking amount of accounts moriartybitcoin. I'll post the list here when I'm finished.
I am not sure why you think KoS is the same person as moriartybitcoin, if you have evidence of such then I would suggest posting it.
I don't think it is a good idea to poison a scammer/criminal as that is something that will generally cause serious legal problems.
In the OP's screenshot, you can see that the account already has negative trust, and if you look at the comments, you will see one from quickseller saying that he is a probable alt of moriatybitcoin, so this claim is nothing new
I found some similarities between those accounts I'll post them here once I get home and you can draw your conclusions about it.
