He posts the links he submitted, but not links to the reddit submissions (such as http://www.reddit.com/r/Permaculture/comments/lf5f1/google_i... ), and there is no link to the submission in r/reportthespammers where they discuss him.

I find that suspicious.

Okay, but his user page shows a 404: http://www.reddit.com/user/gms8994

Maybe that's what usually happens to shadowbanned users; I have no idea.

edit: I can still see at least some of his submissions - http://www.reddit.com/r/Celebs/new/?count=125&after=t3_1... - http://i.imgur.com/pL4bs.png
