Mr Villan Sir...Where I agree in principle to your suggestions being the right approach in "the ideal world", there are a number of reasons why it could not work. Policing(the number of postings on here is vast). administration....takes too much time to organise let alone put into practice. Too many of the "nasties" would not give up but likely play "hit and run" on a number of threads....usually one suspects as GUEST...these people will always try it on.
I would suggest that some are wasting too much time on flamers and trolls instead of getting on with the serious stuff.
Music is my chief reason for being on here..I read a lot and add to some threads but for extra recreation I come to the BS threads for a bit of fun.....My idea of fun does not always concur with others but there ya go...I still have my fun.
Principles are great but not always practical.
My vote is that we all abstain and get on with things as they are. We all have choices!
Best wishes
