"
Thank you."
No need to thank me for using the least controversial word that came to mind - lol - 'interesting' does not IMHO convey a pro or con position on a subject about which I have no personal vested interest. I do not have sufficient information on these past events to give a yes or no answer.
FWIW I suppose Rap and Hip-Hop are 'interesting' forms of what some would call 'music'? I find abstract art interesting too.
Since YOU are the one whingeing about the alleged infractions from years ago, YOU need to run with the ball and initiate action. What have you done locally interacting with the remaining participant in question out there to avoid duplicating any attempts now..... beyond complaining online to us of course? Those here with FAR knowledge have already provided you with their input.
