Bots are not the problem in general, because they are also very useful for many users who have a lot of Steempower. For example somebody has 100 000 SP and he wants to spent everyday 20% of his Votingpower. Because the User has so much Steempower and the effect off each upvote is massive he has to devide his Votingpower into smaller peaces e.g. 5% upvotes. Therefore if he wants to spend 20% of total Votingpower he would need to do 400 x 5% upvotes. That is a huge amount of work to do everyday the user won't be able to achieve this and therfore Votingsbots are a good thing when it comes to spreading your Steempower to the community.
The other point I like to mention is that Steemit will soon become the hivemind update. This feature allows the creation of private and public communitys which also be managed by moderators. So they will have the power to decide which users can join the specific community and therefore he could also decide not to support Votingbots.
