^ It appears QS wants to send the index of the text itself (position of the beginning character of text), and I presume the ending index of whatever is being quoted... and then wants the server to verify the contents of what is being sent and provide its approval.. and also hash it for some reason?.. Why?.. not sure.
That is ridiculous. People post PMs and quotes of posts all the time. There are frequently questions regarding the authenticity of quotes when the original is not available. PM verification would remove that uncertainty.
When the 'original' what is not available? user? PM?... You've already stated the PM has to stay and exist to be verified, and even went as far as to say the PM could no longer be deleted once quoted. So I'm not sure what this PM verification idea is correcting when you say this 'removes the uncertainty of PMs
when the original is not available'. Makes no sense to me.
The status quo is that someone can claim something was said via PM, and the person being accused can stay silent to pretty much guarantee they will come out unscathed. Mods rarely get involved in scam accusations, unless there are large amounts, or a lot of victims involved. If you can prove a PM was sent or received, you can trivially prove you have been scammed via PM.
You're not addressing the fact that someone can cherry-pick a comment from someone's message and make it "verified" by the forum, while spinning a story about what that cherry-picked comment is about. This will give the impression that the forum is verifying the perception being put out by whoever is cherry-picking the quote and saying what it was about. IMO, it adds weight/value to a poster that the forum shouldn't be adding into a situation like this.
The person being smeared better also hope they saved their copy of the message, or they cannot even defend themselves with their own version of a 'verified' message explaining the out-of-context quote.
Let's not mention the fact that this type of smearing could also happen in PMs behind-the-scenes where nobody could ever defend themselves on snips of things they have said privately which would be getting misconstrued to others.
Hell, all of those "impersonator" accounts (or alts, who knows..!) are going to have a great time with this feature self-verifying their own messages from their newbie impersonator accounts with very similar names/special characters, so they can scam more people.
I could keep going, but it's counterintuitive for me.. and this is seemingly a waste of time. <-
edit: To clarify, I'm referring to
my time here, not that the idea
itself is a waste of time. I just see it as a double-edged sword, with the worse-case side sharper than the other, so-to-speak. (especially if the intent is to use QS's aforementioned blueprint.)
Wish you all the best on the idea though!
