I'm sorry, but there is proof linked in that quote (at least the original).
No. Unless I have clearly stated the reason behind my rating(s), all you can do is speculate (assuming you are neutral, which you are not). Unless of course, you want to claim that you can read my mind. 
Actually your definition of "scammer" is more broad than what pretty much anyone else within the community has, and appears to include anyone who disagrees with you..
Absolutely untrue. Trying to mislead new readers?at least this is what appears to be the case based on recent trends, and your history of leaving negative ratings for things that happened a very long time ago that you had been long aware of..
Can you *prove* that I was "long aware of" any of these things? If not, speculation again.The majority of your ratings do not appear to be in line with what the rest of the community would consider to be a "scammer" and you respond to concerns about your ratings with trolling.
Ambiguous claim. I'm certain that almost all of my ratings are in line, and quite a lot of them were backed up later on either for the same reason or after the person had exposed themselves (see Margon as your closest example).
