Twitter CEO Elon Musk relaunched the company's Twitter Blue subscription service on Monday. The relaunch comes after the initial attempt was halted after two days due to a large influx of impersonation accounts.

The subscription service alters Twitter's existing "blue checkmark" function, which is given to an account for free after it is independently verified as authentic. The function was first introduced to reduce the number of impersonation accounts and decrease misinformation from important sources such as government, business, and celebrity accounts.

The new service allows any Twitter user to pay for a verification mark by subscribing to Twitter Blue for $8 a month through the website or $11 a month through the Apple iOS store.

Twitter Blue offers users additional features including the ability to edit and undo tweets, upload videos, bookmark folders, add colored theme options to the feed, and edit the navigation bar among other small additions. The company's website notes that "not all features available on all platforms" and that the features of the service "may change periodically/from time to time as we keep improving the service."

Under the new system, Twitter has stated that a blue checkmark "may mean two different things: either that an account was verified under the previous verification criteria (active and authentic), or that the account has an active subscription to Twitter Blue."

The company is also piloting a Twitter business option which would give businesses a gold checkmark for subscribing to the service.

Twitter Blue's initial launch in November was hallmarked by a large influx of impersonation accounts. Several accounts with blue checkmarks impersonated Musk, including comedian Kathy Griffin, who was suspended from the site and later reinstated.

Another "verified" account used the same profile photo and name as the pharmaceutical company Eli Lilly, tweeting out, "We are excited to announce insulin is free now." Eli Lilly asked that Twitter remove the tweet and the account but after the firing of thousands of workers, no one responded for hours. Eli Lilly later removed all advertising funding from the platform. A former communications official for the company said of the debacle "What's the benefit to a company ... of staying on Twitter? It's not worth the risk when patient trust and health are on the line."

Following the initial run of the system, which was halted after two days, Sen. Edward Markey, D-Mass., called on Musk to alter the verification feature in a letter.

"Apparently, due to Twitter's lax verification practices and apparent need for cash, anyone could pay $8.00 and impersonate someone on your platform," Markey wrote. "Selling the truth is dangerous and unacceptable."

Musk originally set the relaunch date as Nov. 29. Many tech experts are curious as to how the relaunch will play out following Musk's removal of over half of Twitter's workforce, which has led to several lawsuits against the company and CEO.

Musk has said that the platform will elevate free speech even with the new verification system which allows anyone a checkmark if they subscribe to the service. He has continuously called out various businesses and organizations for being "anti-free speech."

Musk, who is the world's richest person, called out tech giant Apple in a tweet, asking if "they hate free speech in America" after Apple pulled advertisements from the platform last month.

He has also poised the site and its users against traditional media.

"As Twitter pursues the goal of elevating citizen journalism, media elite will try everything to stop that from happening," Musk tweeted on Nov. 11. "Mainstream media will still thrive, but increased competition from citizens will cause them to be more accurate, as their oligopoly on information is disrupted," he continued.

"The more Twitter improves its signal to noise ratio, the less relevant conventional news becomes," Musk said in a Dec. 3 tweet.
