Username squatting is prohibited by the X Rules.
Please note that if an account has had no updates, no profile image, and there is no intent to mislead, it typically means there's no name-squatting or impersonation. Note that we will not release squatted usernames except in cases of trademark infringement. If your report involves trademark infringement, please consult those policies for instructions for reporting these accounts.
Attempts to sell, buy, or solicit other forms of payment in exchange for usernames are also violations and may result in permanent account suspension.
