Alright, here's my 2 cents. 2 cents is not a lot, so I will keep it short.
1) I think you abused the coinchat x years ago
2) I think it's weird for Quickseller to add a new negative feedback after such a long time
Personally I think it is unwarranted to put a new negative feedback for something that transpired long ago. Just like it is strange to post again in a long dead scam accusation thread.
