Account holders on social media claim that after confirming their identity, they receive notification that they may now continue trading, but their previously-functional account is now blocked.
The problems, which Poloniex has not appeared to specifically acknowledge, began the same day the exchange issued notice to users demanding they link their identitity with their account.
“We are asking all legacy Poloniex customers who have not provided full identification information in the past to do so now through the Poloniex profile page,” the notice reads.
“This page provides clear instructions on what information is required to verify your account. As soon as you submit this information, we will take steps to verify it and re-enable trading and transactions for your account.”
Frozen accounts appear to affect many users going through verification, with multiple reports confirming the problem persists.
