I'm aware of @randowhale. All I'm saying is that plugging one hole just forces leaks to come out of others. I'm an original advocate of preventing all bots from voting, and have posted how this can be done.

Even though selfvoting and circlejerks would still be a problem, that problem would at least be something actual people did, rather than devices. I reckon infesting social networks with bots devalues people, and find that more offensive than financial problems themselves.
