Hmmm. I wouldn't recommend the basic stuff like Jeff the Killer or ben drowned. They are a little cheesy and sometimes not well written, unless you are into that sorta stuff, like me.
Some good ones are Godzilla NES and Lost Silver, and maybe the Russian Sleep experiment.
It's not really a creepypasta but...EverymanHYBRID is a good web series! Our little friend HABIT comes from there!
