Apparently he isn't breaking any rules,if he's constantly annoying you, you can simply put the user on ignore..
Sadly he's one of those who make high rankees put the entire section on ignore...
That's the best option, IMO. And Bitcoin Discussion is one of the sections I have on ignore, but it's not because of members like him--it's all the stupid nonsense replies to threads started by people like him and others with nothing useful to say.
Hydrogen almost exclusively posts news snippets in the Economics section, but the big difference is that he sparks the discussion on them by posting some of his own commentary after the quote--and both the news quote and Hydrogen's input are usually worth reading.
I think if a post is being made just to promote a website that is owned by the poster, and the site is not of benefit to Bitcoin Talk or its members, then the post should be deleted.
If that's the case, I'd consider it to be spam and it
should be deleted. I've reported quite a few thread OPs that are just link spam disguised as a discussion, usually done by brand new members.
