You can't really stop bots. Like you can't stop spam, plagiarism, insider trading, crime, infidelity, and the list goes on.

People who are skilled in the trade love to make bots because they can and because they can gain some kind of reward in it. Making a stand saying we must stop bots is going to do practically nothing.

Bots are all over the real Internet and it seems to be working fine. Yes the owners of sites have to mitigate against bots and certainly should steemit but the problem will always be there. Never going away.

If you go to http://piston.readthedocs.io/en/develop/ one of the command line tools for steem they even give you a simple explanation on how to build a bot. Bots are like guns they are as good or bad as the programmer who uses them.
