Proof? Do you have your charity information?
"Running a scam coin claiming to be a charity, but refusing to provide proof of charity as required by law.
What else do you expect from someone who preys on gullible people?"
Disclaimer: I like the coin and I am involved in the community to try to make it better. I also run the block explorer.
I find that feedback rather harsh and borderline dishonest as the "refusing to provide proof" did not happen.
It's just nobody saw that message since you posted it a thread that nobody checks? Maybe posting your question on the main thread, reddit, or anywhere else would have been better.
I do not want to sound harsh myself but you barely waited 2 days before coming to that conclusion and you did not even take the effort to spend 5 minutes to post it on the main thread after you had no replies here. I know you have good intentions and want to protect people from scammers but I think you made a mistake here.
I really hope you make it right and remove your feedback and possibly provide an apology or at least a corrigendum after reviewing the evidences (you can probably ask for more evidence if that link posted above doesn't satisfy you).
