The Reddit user's neopets username is xdem0nicx. It's an old shell that suddenly had it's name changed from Anthony to Zach about a week ago (week ago).
The reddit post was titled 'Iced a few accounts
' and the post (which has since been removed) only mentioned one of the users by username, 128x128.
Others that were frozen in the same timeframe:
hiraanitiger
incogniti
stromlazer88
These users were worth hundreds of millions, probably billions of neopoints.
Zach got removed from the r/Neopets discord server because after getting called out by MJ (128x128) for buying a shell, he flipped out and called a bunch of people fa**ots and other
outrageous things. Then he got removed from the Snipers United guild (no relation to the old SU (RIP)) because the council became aware of his buying a shell for the purpose of restocking.
It looks like he had a personal vendetta against MJ, as well as the council members of Snipers United. I think only one council member remains unfrozen.
