If I post my password on the Internet and someone uses it to get into my account, is that still considered hacking? And illegal? [serious question]

I guess if I lost my wallet and someone finds it and uses my debit card, I'd consider that stealing.

The CFAA (Computer Fraud and Abuse Act) prohibits unauthorized access. If you find a piece of paper with an account name and password written on it and use it for access, it is illegal.

If you lost your house key and someone came into your house and looked around, that'd be trespassing.
