EpicNPC + PlayerAuction are 100% "identity thieves". (since they advertise each other, I'm guessing they're affiliated/partners)
Some people on Graalians already knows my whole story about PlayerAuction and how they stole my runescape, habbo accounts.
This time it's EpicNPC.
Today, my alt that I created for multi-purpose got critical security alerts from Gmail and It was attempted login notifications from some African countries. I have my documents for all the sites that I signed up and it was matching to EpicNPCs info. (This account was rarely used on sites, in fact, it was my Google review account)
Anyways, idc if u use playerauction or epicnpc, but make sure it's all fake info + weird pw. also when u are trying to sell account, put fake info there as well. cause they don't even check. then u can msg the buyer the pw thru discord or something.
