The only 'bot' I delegate to is @isotonic that supports the running community. My issues are with the big ones that give massive votes to posts that don't really deserve that. I have delegated to @steem-ua as they seem keen to help the community and I get something from that.
I wouldn't miss the 'bots' if they went, but I don't see any way to actually ban them.
I guess my answer is really c as I curate manually anyway.
Your 'shit post' has done pretty well.
I have not looked into @isotonic, but see you are not the first to mention it.
@steem-ua look to be distributing stake better than anything else at present, and have my support too.
Shit-posts can be engaging too I guess :D
Some 'shit posts' may be funny, but I won't do anything to encourage those who use them as an excuse for a big self-vote. They are not helping matters at all, but they can get away with anything as nobody will take them on.
