A Grey Hat SEO Idea

I have considered this for 2 weeks, and I have researched a lot for it. Im planing to promote my products by forum marketing and blog marketing. I will set up 10000 niche related forum accounts and 1000 free blog sites , hope to get traffic and back links from forum signature and blog sites. I will write 100 original topics and spun them for 10000 forums every time, and write 10 original articles and spun them for my 1000 free blogs every time. To prevent my accounts from banning, I want everything done like a natural human but not a robot, so I need to manually reply the topics I posted once or twice . I will spun all the signatures with the most of my main keyword and ping every backlink to the bookmark sites later. I think, I will get at least 500-1000 visitors from forums, blogs and search engines.
It is hard to do it manually, you need to hire a lot of people to do it for you, but I want to do it myself. To do it, I need at least 4 auto tools: Spinner, Auto Forum Submitter, Auto Blog Submitter, Forum Topic Tracker. Something I have found: The Best Spinner, Xrumer , Google Reader or Forum Topic Tracker every forum has. I have bought The Best Spinner, it works great, and I am going to buy Xrumer, but I don?t know whether it can reach my goal, as I know, it has done well on account register, topic submitting, and blog comment spam, but I don?t whether it can submit my article to my own blog sites.
Any Advice is appreciated!

That looks like alot of hard work and alittle confising, i wish you all the best with it.

Yes, there are a lot of hard works, but it is a long term success
