What “threats” are you talking about? This?
If so, what “threat”? They seems to be asking you to provide evidence for your claims of their alleged wrongdoings, lest it be considered libel. That doesn’t seem as any “threat” as you seem to imply, if you ask me. In fact, libel is exactly the same thing I warned you to refrain from in my post above (which you 
-ed - and yet here you seem to complain when others warn you of the exactly same thing?)
Also, you should’ve produced the supposed evidence in the same post where you accused them of alleged wrongdoings, instead of “I’ll provide proof at some indefinite point in the future”. That is ridiculous behaviour. You need to provide proof of your accusations ASAP, or hold your peace forever after, eh? Does something so obvious really needs to be pointed out?
Especially seeing that you’ve seemingly had grievances with those mods for more than a year now, one would expect that you would be ready to spill all that evidence on the first hour of the first day of that moderation thread coming into existence!
I try hard to afford people second chances, and to take posts in good faith by default, (regardless of previous behaviors of posters). I like to think that people should be given a second chance, for a hope that some would repent on their old bad behaviors and try to improve how they behave in the future. That goodwill is however not a license to go back to bad behaviors one has already been sanctioned for in the past. Please don’t waste that chance. You can do better and provide valuable input to community.
Can anyone with super moderation powers go there, remove this threat,
As the saying goes, be careful what you wish for, as if people with “super moderation powers” stumble upon such shenanigans again, they might as well decide to remove the perceived community threat.
