Twitter’s relaunched premium service, which rewards ticks for anyone willing to pay $8 a month, was unavailable Friday after the social platform was “flooded” by a wave of fake Twitter-approved impostor accounts, The Associated Press reported.

Before billionaire Elon Musk took control of the social platform two weeks ago, the blue tick was given to celebrities and journalists verified by the platform specifically to prevent impersonations. Now anyone can get a checkmark if they have a phone, a credit card and pay $8 a month to the company.

Pharmaceutical giant Eli Lilly & Co has had to apologize after an impostor account registered on Twitter’s updated Blue system posted a message claiming insulin was free. In addition, Nintendo, Lockheed Martin, Tesla and SpaceX, as well as the accounts of various professional athletes, were victims of such accidents.

An email for reaction was sent to the company’s Twitter account, but did not receive a response. According to the Associated Press, the company’s communications department is currently decimated by layoffs.

There are currently two categories of blue ticks that look the same. One includes accounts verified before Musk took over. It states that “this account has been verified because it stands out in a government, news, entertainment, or other specified category.” According to the other category, the account is followed by Twitter Blue.

For advertisers blocked on Twitter, the fake accounts could be the last straw as Elon Musk’s new policy at the helm of the platform, which has led to half of its staff and high-profile layoffs, casts doubt on its survival.

There have been a few stutters this week already.

Musk tweeted on Thursday that “there are too many broken old flags, so the only solution is to remove the blue flag in the coming months.” Twitter Blue was not available on the online version of the platform, which indicated that registration was only possible on the iPhone version. However, the iPhone version did not offer Twitter Blue as an option.

Twitter has also started adding gray “official” checkmarks to important accounts again. The company released the tickers earlier this week, but removed them hours later. The ticks reappeared Thursday night, at least for some accounts, including Twitter, as well as those of major companies such as Amazon, Nike and Coca-Cola, but then some disappeared again.

Also, many celebrities have not yet received the “official” tick.
