Is it just if a user email and password is changed so he deserves negative trust?
If so then many people will abuse it ,if someone changes his password then someone will make new account and start claiming that his account is hacked.
Wrong. I've said a combination of both, and it's trivial to prove that you're the original owner. If you plan to both change your email and password, you might as well prepare a staked address.
If he has given negative rating based on posting traits and behavioural writing the he must mention it in reference or comment.
Anyways i appreciate his caution as the account in question is dt account but not always all allegations are true and he might end up fighting like tman and ognasty at the end.
This one was the right call from KWH, whether you like it or not.
I would add today's date ASAP.
I think it is adequate as is, given the uniqueness of the message but yeah.
