I was thinking about all these topics in BST and private blog network sellers. It is nice if someone is selling 100% unique content, No report , No footprints and limited spots But what is the point of buying it when he will probably close the network when domains will expire? You will lose all links and if you lose all links at the same time from many domains with all other "unique spots" in network guess what? You website will die Or do you really think that someone will pay for domain names if there is written "limited spots" ? So only point for buying these links is churn and burn or?
