I believe the British Airways site still does something similar to this, or it did until very recently if it's been fixed. Add a password that is too long, it gets truncated and the truncated version saved with no warning or error.
It took me several password reset attempts to realise what was going on, as my literally just set and password manager-saved password didn't work.
I think in BA's case the password input also had a character limit on it, which is ultimately how I realised what was happening, even though there was no info anywhere that such a limit existed.

Worth recognising that each subreddit is its own community, and like individual forums, will likely vary wildly by subject. My experience of subreddits for my interests and hobbies is the opposite to yours; information is correct and discussion useful.
In my experience that tends to only be true in the larger subreddits. The (potentially) more niche subreddits I use don't have that same problem outside of maybe a 'read the FAQs before posting'
Walkers lost the case.
