Why not make an effort to contact the people he told you to, or to
email him directly and ask for the contacts? It takes very little effort to call people out on the internet....if JV allowed himself to respond to everyone who decided to just 'kick his tires' he wouldn't have much time for anything else. So I think it's up to you to demonstrate that you will make some effort to get the information. That effort is about the only way that you can demonstrate to JV that you are prepared to consider his side of the story. If he has no reason to believe you will consider it, why would he waste his time interacting with you?
No. You set the bar when you demanded that he speak publicly about his doping. I think your criticism is premature and unreasonable. I also think it greatly reduces the chance that you will get any further information out of JV.
Basically, by publicly stating your assumption that JV is managing this situation/playing on your good nature, you are not acting in good faith. There could be reasons why he didn't get back to you yet....perhaps he hasn't checked in here since you stated that you didn't intend to contact the people he suggested.....perhaps he expected you to contact him outside CN and assumes that, because you haven't, you aren't serious....who knows? But good faith would be assuming the best, assuming something got in the way of JV communicating with you and making another attempt to contact him, before making negative public judgement.
I think that you are failing to see this from the other side. You might know that you are well intentioned and able to be reasonable, but JV doesn't know that. He has just been on the receiving end of some pretty harsh statements from you. Although you retracted the most personal stuff, he is unlikely to have forgotten it. I think he is entitled to some consistent tolerance and patience from you, before you expect him to take you seriously or believe you are genuine.

Frustrated. Don't know how to communicate to you that you're still coming across as quite belligerent and unreasonable. Decided try a different approach.... FAIL?
