You obviously know nothing of blackhat SEO if you think I am concerned with a site dropping from the index, I probably lost a few domains writing this post. Adsense account? Check. Hosting? Check. ISP? Check. I'm good to go.
Ofcourse not, and dont even think about comment spam. It will be of no use at all lately, because of our friendly attribute (rel="nofollow") Check out more details here http://googleblog.blogspot.com/2005/01/preventing-comment-spam.html
Link spamming was never a good option in the first place. You need to invest in quality content, and as long as you regularly post it over a span of 3-4 months, you will see your organic rankings steadily and permanently rise. There are many, many services that can make quality, unique content for you, check fiverr for some cheap ones.
you cannot spam any more, it not only gets banned but the places where you can do it there is so much of it that people don't read it people want to buy off someone who knows what they are doing, that means giving relivent content out with your links the three marketing strategies I use are Ezine (this one has got most of my leads), social networking (create a facebook page with something that interest people and advertise the product that way) and forum marketing hope this helps
Totally Agree! Link spam will get you into hot water! You need to focus on quality hand-made backlinks. Why not use a quality backlink service and focus your energy on building your business
