Hi Everyone, I am following guides posted on this forum to help me on my path, Building niche websites in the hope of selling through Amazon and getting a few extra ££ from adsense. I have bought 5 domains, and it's my goal to have them ranked and getting traffic ready for Christmas Now I am not afraid of laying down some money to source unique content. but I am also looking to use some of the darker arts for SEO, commenting, and backlinking, and many other tools highlighted in various guides on this forum. My question is how far can these tools be used before you run the risk of being sandboxed? penalized? I have done a lot of reading here and many people are having problems with this and many seem to not be using the arsenal of black hat tools available to them? are pages sandboxed frequently, how far is pushing the envelope? Any rules of thumbs, tips for avoiding the wrath of the big G would be much appreciated.
