IMPORTANT: Allegedly hacking accounts

Dear friends,

Over the past 24 hours, many users received service messages stating that somone was allegedly trying to hack their account. The attacker's script is rather primitive and is aimed more at psychological pressure than at real theft of the account, in such cases we limit the sending of such messages to a minimum.

What you need to do: make sure that your password is not easy to guess and just wait, the protection script is configured in such a way (without specifying details) that the "well-wisher" simply self-cuts over time.
All patience and kindness!
