The inactive accounts, in this proposal, will be moved to a cold archive after a prolonged period of inactivity, ranging from 6 months to two years. The cold archive consist of:

1. A separate subdomain from main Twitter. Example archive.twitter.com or limbo.twitter.com

2. While accounts retain their original usernames as part of archive usernames, their mainspace usernames will be freed up. Discord-style number discriminators may be used so to prevent archive username exhaustion, although keeping their names intact during the process is ideal.

3. If an archived account is accessed, there will be a prompt to ask whether to restore to mainspace or leave it as it is. In the case of the former, their mainspace usernames are usually restored, but if someone else has taken up the slot then they have to choose a new username.

4. Past search histories that are related to the account is deleted upon archiving.

5. While as in normal mode, tweets and users can be browsed through its internal search engine, a robots.txt will forbid Google and other bots to index any and all contents of the archive subdomain. Exceptions only apply to Internet Archive's bots.
