Yes. When I was younger, before I was capable of any programming (but still somewhat technically competent), I used to visit the freerainbowtables.com forums.

As it happens, I 'rediscovered' him on twitter via another hackernews post [1] a while ago, so dropped him a message to say thanks for being an unwitting inspiration :)
