The 180 day rule
TikTok says an account that has not been used to access TikTok for 180 days or more may have its username reset to a randomized numeric username.
Nobody else can see it
TikTok says whether an account is inactive is not publicly visible. A profile with no recent posts may still be in use.
Reassigning is the exception
TikTok says that in most instances it cannot reassign a username.
Routes that fit real facts
An impersonation report fits an account posing as you. A trademark report fits a registered mark and needs a registration certificate. See the TikTok claim page.
