This comment is however NOT a defense of bots. I think bot detection and deletion of bot accounts would be a good thing.
But the concern seems out of proportion.
Society is full of disingenuous message amplification systems: a large subset of advertising (TV, magazine, billboards, direct marketing, etc), biased news media, spam, and now twitter bots.
Twitter bots are a bit worse than the others because we can no longer tell what opinions are actually popular and which ones are manipulated... via Twitter. But the ability to make such judgements via Twitter has only been with us since 2006. The basic problem is not a novel one.
The bot problem cuts both ways because people will overly compensate. I've been accused of being a bot, signalling to everyone that it's perfectly OK to ignore the content of my argument. I fear many other right-leaning people are getting the same treatment. This treatment further divides society (actual bots do too, which I am NOT defending; I'm just showing that the issue cuts both ways). Other commenters in this thread have been flagged and their comments are dead apparently because (if you believe surrounding comments) they are seen as a bot.
The day that Twitter becomes a voting platform, or voting platforms allow bots... that is the day that I will panic about bots.
All that being said, carry on. Let's squash the bot problem. Let's also fix advertising. Let's also fix news media bias. And spam.
