I don't think the "password changed" message is something meaningful. That is the widespread practice in password changing on regular basis to increase security of the account. Some services even force you to do that from time to time, IMO.
There are some factors to consider potential scammers.
If you see one account (in Trust page) shows both of:
- "This user's password was reset recently."
- Woke up recently (I don't remember the exact words).
The title is "Password changed / Woke up recently." More exactly, it should be password change and/or woke up recently. If you want to add more email changed recently. In previous posts, people mentioned about BPIP, that I know too. Unfortunately, the site is in updating progress and we might see a totally new version of BPIP soon.
You can combine all three factors:
- Password changed
- Woke up
- Email changed
All done recently. However, in my opinion, only the first two factors are enough to be more cautious with such accounts.
