Once @nextgencrypto was asking me what was the purpose of programming the bot -- the question was directed towards @jeeves the content linking bot -- and I answered we are just doing an experiment to see whether there is a room for a bot like @jeeves and whether community would find it interesting.

I think a lot of devs saw @wang how it was able to get rich so quickly and perhaps that's their motives of creating these upvotting bots with the hope of making $$$$$ from curation.
