I read somewhere on the forum that if you do not login or make any post here for 3 months , the account is deleted. Can someone confirm this as I could not find anything official about this.
If you don't login for three months, your account gets locked. It does not get deleted, ACCOUNTS NEVER get deleted under normal circumstances/ without the owner's request and signature.
Similarly, the owner needs to sign to say that they want their account to be unlocked. The main way to do this is to sign a staked address/another public key.
