Somewhat of a dangerous precedent to demand that people give up transaction ID information or else they are deemed untrustworthy. Seems counter to this community saying that privacy is such an important thing around here. Not saying OP is or isn't guilty or anything. I'm just saying that the reasoning that I'm seeing for the negative feedback is questionable at best. Far too many people around here leave negative ratings because their feelings or egos got hurt. Those folks probably shouldn't be anywhere near the Default Trust network but it isn't their fault they are, it's the fault of those that include them.
I don't think that anybody would demand id as proof if there was no serious doubt that the transaction took place.
OP was trying to promote the thread somehow, the guy who took the job was a new account who never worked for anyone, had no trust, no history on the forum whatsoever.
How would an honest, transparent person respond? Maybe show a screenshot of the transaction with parts of the addresses and the txid blacked out. Ask the "client" to respond and explain if maybe he wants to show the id. It's not like we're talking about millionaires doing business here. OP obviously wanted to make a name for himself and be seen as trusted, so why would he backtrack so much when asked for that transaction?
With how he reacted afterwards, trying to manipulate trust and retaliate with negative comment, I'd say he was guilty in the first place. He showed his true colors, just needed a push to do it.
Except for the added sneaky hurdle of clicking - "Show Ratings". So sorry, not it IS not working - or maybe is in a way to discourage people from viewing the so called Untrusted Reviews directly.
Anybody can give anybody untrusted feedback. If there was no distinction, you'd be able to make 50 accounts in a day and flood someone with positive or negative comments for all to see. It would make no sense.
