by far, i know black hat tools, including xrumer, scrape box, autopligg, Prstorm, link farm evolution, etc. my question is if i want to bring large traffic to my sites, and to save money at the same time, which black tools should i buy to use? don't tell me to buy all of them, i am not that rich. is just xrumer enough? and could anyone tell me how to use xrumer and scrapebox, i have never used them before. thanks!
