So you never had anything to go on, but an anonymous tip[1]?
I'm not sure you could call it anonymous - Shadow_Runner - hero member almost two years old with 6,000 posts.
You do realize that Shadow_Runner was quite obviously a recently sold account, right? It might as well have been a newbie with 3 posts.
I don't think this mattered very much to Vod. He has a solid history of not conducting any meaningful amount of research prior to leaving negative trust against someone (or in this case doxing someone), and when he is called out on such negative trust with the lack of evidence, he simply trolls them until they leave.
Why would this case be any different?
