Inactive account policy
What is Twitter's inactive account policy?
We encourage people to actively log in and use Twitter when they register an account. To keep your account active, be sure to log in and Tweet at least every 6 months. Accounts may be permanently removed due to prolonged inactivity.
How does Twitter determine inactivity?
Inactivity is based on logging in. Please note that you may not be able to tell whether an account is currently inactive, as not all signs of account activity are publicly visible.
What if a potentially inactive account is using my registered trademark as its username or account name?
If you believe your trademark rights are being infringed and the account seems inactive, please see Twitter's trademark policy for additional information.
What if I have a request for a username from an account that looks inactive, but I don't have a registered trademark?
We do not generally accept requests for usernames that seem inactive. If a username you would like is being used by an account that seems inactive, you should consider selecting an available variation for your use on Twitter. In general, adding numbers, underscores, or abbreviations can help you come up with an available username.
