No more than 2-3 weeks ago a read a thread talking about getting easily 10 000 uniques from a listing on reddit. I saved the thread, but now when I tried to see it again it doesn't exist. I suppose it was deleted for some reason, but if some other guy remembers something please share it here.
the gist was find a cool picture and post it under pics. go blackhat and use multiple accounts and proxies to bump your pic up and bump others down. I found that the same applies towards articles, videos, etc... gl.
Dunno but here is a good digg method -- http://www.blackhatworld.com/blackhat-seo/making-money/37770-get-digg-domination.html
