A hundred worthless bot downvotes add up it's also more about how they are used more not as a way of curating content but as a way of persecuting people who don't agree with whales have different opinions than majority of community etc 
In short I think downvotes if smthng should be aimed at what is said I something  not at who says it while with downvote bots targeting a user where is the content curation? It's just a way of bullying people of the platform, not really the land of free where there is no tyranny or racism as many claim steem is( personally I think most of those people either have there heads burried deep in sand or never had a thought of there own)
