Lets see, you asked "where is proof of threat", you have been pointed where to look and then you went 180 degrees.
In the real world, the one who claims that I threaten h4ns has to quote where?

Those are your words GP, take your time and read this part: "
threatened to get sued", did they THREATENED to sue you for DEFAMATION?

So you can't sue h4ns because you will reveal your identity then and you obviously risk serious charges and in real world without lawsuit your defamation case makes no sense.
It is best that you just return 210 and get over with it.
