Well, the fact that Shadow Joe singled me out was a dead giveaway that he was Harold E Hall, but there were also a few other details which revealed his real identity. For example, during that explosive bout of tard rage he displayed, he linked to the statutory rape thread on TV Tropes. The ED article about him never linked to the statutory rape thread. That's an awfully specific detail to point out, don't you think? He also referred to a "rude girl". That would be lolacat, the girl he stalked back in 2012. He also referred to Anime Reality. Again, more proof that he is actually Harold E Hall. And even though he repeatedly claimed he wasn't Harold E Hall, he behaved just like him, from his irrational hatred of TV Tropes to his habit of writing up long, rambling, incoherent, rage-filled diatribes whenever someone makes him butthurt. He thinks he's a master of deceit, but he lies just about as well as Chris-chan.
By the way, I searched for Harold Hall on Instant Checkmate and I came across this:
Apparently, Harold E Hall has a criminal record. Problem is, you need to pay money in order to obtain these records. Okay, I'm really curious to find out what he did. Perhaps it might explain why he's so emotionally invested in the issue of statutory rape.
