I can totally see that. I was banned from my old forum when a mod shared my personal information with a protected poster, since then I have had an attempted swatting, someone calling my work, home and cell harrassing me with threats and all that, as soon as he realized this he reached out to them and posted thier lies here. my crime to get him to do that?  showing up here. 
I have his personal info, he wasn't hard to find. I have litigation and a restraining order against the former forum and he thought is respectable to intefere with that, he's a scumbag and if he want part of that lawsuit, I will oblige if it makes sense on my side. 
people should not seek to be assholes to another,  he is a manifestation of us losing that insight.
