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.
It may be weird but IMHO there is valid point for adding a negative trust though I don't know what's Quickseller's intention.
- 2.5 years ago TF was in default trust list.
- tspacepilot earned Bitcoins from coinchat using bots.
- TF added a negative trust feedback and was in trusted feedback.
- TF was removed and the feedback went to untrusted feedback.
- Quickseller bumped it because that is a scammy behaviour.
- Hence, everybody can see his scammy behaviour.
Leaving negative feedback for things happened long ago isn't unwarranted/unjustified.
