Account Lockdown: Unusual Activity Detected

hey, a year ago I lost access to one of my gmail accounts, now I was locked out, and the automated support didn't provide any helpful solution, only thing I know is I'm locked out of my account for the next 24 hours, with no apparent reason. and no phone number to call. I'm thinking more and more in not letting go my ISP provided email service.

This account has been locked down due to unusual account activity. It may take up to 24 hours for you to regain access.

Unusual account activity includes, but is not limited to:

1. Receiving, deleting, or downloading large amounts of mail via POP in a short period of time.
2. Sending a large number of undeliverable messages (messages that bounce back).
3. Using file-sharing or file-storage software, browser extensions, or third party software that automatically logs in to your account.
4. Leaving multiple instances of your Gmail account open.
5. Browser-related issues. Please note that if you find your browser continually reloading while attempting to access your Inbox, it’s probably a browser issue, and it may be necessary to clear your browser’s cache and cookies.

Sending limits


In an effort to fight spam and prevent abuse, Google will temporarily disable your account if you send a message to more than 500 recipients or if you send a large number of undeliverable messages. If you use a POP or IMAP client (Microsoft Outlook or Apple Mail, e.g.), you may only send a message to 100 people at a time. Your account should be re-enabled within 24 hours.
