"Marked you as a spammer" and "promote fraud" is your interpretation, and I believe it's wrong. A single person called your comment "link spam", that's it. And nobody even mentioned fraud.
You seem to think fraud could be the only reason for a flagged-off comment. It's the rarest reason. I cannot remember a single clearly fraudulous comment here.
And I'm sure the people who flagged my submissions and comments from time to time didn't think they were fraudulous, either. They thought they were obnoxious. Or combative. Or mean-spirited. Lots of reasons why someone might flag something.
For what it's worth, I don't think you're trying to defraud anyone. Still, I believe that this cryptocurrency you mentioned is probably fraudulous, as are all of them. :-)
Yes, you linked to ycombinator. Among other links. Nobody ever said anything about that particular link. Again, it's your imagination.
Thanks for full-quoting your comment, but that wouldn't have been necessary. I have already read it. Before flagging it.
I don't care much about you taking your words back, and your pathetic attempt at blackmail doesn't change that.
Finally, yes, HN has changed a lot. In my opinion for the better, but you're in good company, many readers lament that change. Personally I don't particularly respect (or disrespect) Paul Graham, and I'm glad this isn't a Paul Graham fan site.
Maybe it really isn't for you. Do you really want to put more energy in this fight?
