Could be fun ! :D
A few people tried this a few months back and were swiftly destroyed. It could be fun, and it could also be the last thing you ever do on Steemit. I would advise you to tread very carefully here.
There are bid-bots like Smartsteem that filter out the abusers and spammers, and I see absolutely nothing wrong those types of services. Bid bots emerged as a result of Steemit's faulty curation algo, so as far as I'm concerned, these services are filling a need.
