[2020] Logged in to my name gone

Logged in this morning to my account named Samphetamine to see a window stating that I must choose a new account name.

There was an account with the name of something like "I report you" following me yesterday saying "I've reported you for offensive account name" so I'm assuming this is why I currently don't have an account name.

If a J mod could please look into this for me I would appreciate it, as my name is Sam and I love the account name Samphetamine, its been my go to for all games.

Thank you
