In an egregious example of the "blue checkmark" scam infecting crypto-Twitter, a fraudulent account that recently aimed to dupe users of the cryptocurrency Verge moved onto Bitfinex – that is, before going dark completely.

The Next Web reported Wednesday that freelance film producer and director Seif Elsbei's verified Twitter account (@seifsbei), which boasts Twitter's coveted blue checkmark and over 83,000 followers, was posing as the official account of the Verge developers. The cryptocurrency was thrust into the limelight Tuesday with the news that Pornhub would accept it as a payment method.

Verge's real account, @vergecurrency, lacks a verified checkmark, which the hacker behind @seifsbei perhaps saw as an opening. Twitter allows verified users to change the display name of their accounts without risking their verified status, so @seifsbei adopted the display name vergecurreǹcy. They then proceeded to retweet messages from the actual verge account.

Shortly after, @seifsbei moved on to impersonating the exchange Bitfinex under the name Ƀitfinex.

A Google search for the account indicates that it was impersonating another exchange, Bittrex (as Ƀittrex), prior to posing as either the verge team or Bitfinex.

As The Next Web points out, the account's controller has previously masqueraded as ethereum's founder Vitalik Buterin. Retweets from the @bitcoin account suggest they were also posing as that account as well as that of the Tron project.

Prior to this week, @seifsbei tweeted almost exclusively in Arabic. Elsbei announced on his Facebook page Tuesday that this account had been hacked and that he was working to recover the handle.

After being contacted by CoinDesk, the account removed its banner image and avatar. Its username is now "." As of press time, the account has not lost its checkmark.
