Just my opinion but I think you should take a step back from tagging people. Not entirely, but it does feel like you are actively trying to search for new reasons to leave negative feedback. In contrast to coming about it organically through time and experience what you deem to be worthy of negative feedback. Ther eare areas where you are confident in your leaving of feedback and I would focus on that for a bit.
I say the above because this
And yes I noticed from my untrusted feedback. He/she left me negative feedback because
I called scam to BitcoinSV. According to this user SV is potential coin, lets say he/she is right. So if someone call scam to SV he/she deserve negative feedback on his/her opinion. But if someone call scam to bitcoin then he/she is deserve negative feedback in my opinion.
If we are negging people here for a differing opinion then this is no longer a discussion forum. Obviously the majority of us disagree with them and they may just be trolling. Either way a difference of opinion should not result in a Neg. Personally I feel like most opinion and behaviors are deserving of a neutral as opposed to Neg or Pos feedback.
Just look at the feedback they left you. It seems really stupid right; and it was left solely because you differ with them on the opinion of a coin some people believe in.
In regards to the HEX stuff look into it. If it appears to be a scam, I like the approach Marlboroza took with similar scam promoters Iirc. Tag them with instructions on how to purge all advertising done at a minimum.That or warn them before the tag and give the same ultimatum.
Definitely report the referral link as that's against forum guidelines.
Again just my opinions, your feedback is your to do with as you please. Not trying to single you out just something that's been on my mind the past few days.
