I just read this thread as well.
I had been on vacation for a few weeks when this started and then had some private business come up over the last couple weeks as well. I've been popping in, but I think I had skipped it because it said Grave Digger in the title
I was here all spring and summer while we were getting GD posts. Like some people here, I didn't find his initial stuff too bad, but he certainly seemed to be working on SEO. I eventually stopped opening them or never read them through.
Although, just for anyone who really wants to know, hundreds of the same links in your signature on a forum (blog) to the same URLs from the same based domain don't really amount to much. For example, my signature links. If I have 3 posts or 900 posts it won't make much difference. What will make a difference is whether the search engines (SE) find those threads to be valuable information to the Web world. If so, that thread will do well in the search rankings and your signature links or website links will be of value, especially if they are relevant.
Something like a tutorial on
how to make a sarcophagus, ideas for an Egyptian theme Halloween party

or what's the best way to sculpt and and paint foam for headstones. Those are what people want when they search for things, good relevant, informative or helpful information. But it's not only valuable for the links involved, it's valuable to the site that it's on. So when we post our stuff here, it's very helpful to ZombiePumpkins. It makes this site more of an authority in other areas beyond pumpkin patterns. It gives credit to the site for Halloween decorating, props, eerie artwork and as that authority grows it also increases the pumpkin pattern authority as well.
Point being, even if you are just marketing, it's better to make a few good/helpful posts than 100 fluff posts.
