Nah. Both are trolls but PG is more intelligent and entertaining as annoying as he may be. Cryptohunter is a special type of moron who has gone full retard. I think he actually goes way past being a troll and actually has some mental issues that have either been caused or certainly exacerbated by this forum hence his need for validation from everyone here and his desperate over-compensating. Whilst I can see why you suspect them as going awol and another account signing up the same time is a bit suspicious, if we were going by that then there's lot of other accounts that you could link, but that alone isn't enough proof especially given the lack of anything else tying them together and dates of users registered/going awol can be deceptive and misleading. I used to think that Big Boobies talkinDoubleD and Nigerian CocoPalm Farmer belonged to the same group of trolls as The-One-Above-All/Cryptohunter but that was very likely not the case as other evidence presented itself over time:

They all had a beef with signature campaigns and made the same sorts of threads complaining about mods and given their registration dates it looked very compelling. The-One-Above-All's first post was even a response to a thread Nigerian CocoPalm Farmer created: https://bitcointalk.org/index.php?topic=5130756.msg50561852#msg50561852

But it was just a coincidence and they were actually a separate group belonging to this guy that was exposed eventually: https://bitcointalk.org/index.php?topic=5184777.msg52461972#msg52461972
