This thread is frustrating. Everyone seems more interested in nitpicking the specifics of what OP is saying and are ignoring that a forum sends you your password (not an automatically generated one) in an email on registration.
The one they were sending at registration was prior to hashing. It would not be reversible afterwards.
That’s technically less terrible, then.
Good for them. /s
Edited to add the /s for clarity, because the NIST recommended remediation in 2023 for emailing a password is “burn everything down and pretend the organization never existed”. /s
Again, adding that /s since that’s not actually what NIST says to do, and I am, at best, paraphrasing.
