Others can fill in as to the reasons why if they want.  The only information I have is this from a post he made a few days ago  on SH:

"Well its has been building up for a few weeks. I don't like the style of certain individuals. I had a few posts deleted a few ago...since then the place has just annoyed me!".

I'm not sure what thats all about either.  Anyway, apparently he is now at Investorvillage if anyone is looking for him.
