OP is asking me to remove my feedback for a successful trade because of what happened to them.
I don't think you should remove anyone by anyone's speech. But if you think that person is a scammer or can scam then you should remove it without anyone's speech. Even trust can be the opposite positive to negative.
Please proof the messages by forwarding to a trusted user.
Check if my username was @ambosss
I don't think op can proof it because telegram is the easiest way from where all chat information can be removed within a second. And telegram username can be changed also at the same time a new account can be created on the previous username.
Can be deleted from one side, as it shows in the screenshots , some messages are old already and can't be deleted on both sides. At least him should have the conversation and can share it easily.
HCP - yes, it can be changed within a second, i always ask people to use minerjones as he is fast as always on telegram, not my fault he was played by someone.
Next time take care and use escrow
Solution, get in touch with someone that posted in this channel and forward the message where I gave you an ADA address. They can check if the message comes from me or not, whatever the username i had at that moment. it will show the current one.
