All I see now are 2-3 minute old post with mountains of votes from new accounts that barely have any steem power. This has a very corrosive effect on the network imho. First of all, any posts that gets these votes will most likely not be upvoted by established members as the bot accounts would essentially be profiting. So this actually damages legitimate posters and may have a very destructive effect on the network over time.
These small bot accounts may not have much sway right now, but over time their voting weight will begin to accumulate and these Steem bot networks will then start to be leased to the highest bidders on various blackhat forums.
As word spreads about the money being made on Steemit, the amount of bot behavior will increase a great deal. I f***ing guarantee it!! The devs and the community need to address this issue right now!!
