I always assume that probably 95% or more of accounts on Twitter are fake, based on my experience. Back in 2017 or so, when QAnon was being heavily pushed by botnets, there was what looked (to me) like a leftist analogue of it[1] being pushed in the same manner, and it just didn't catch on the way QAnon did. I figured it was probably being promoted by the same people, to inflame tensions in the US. Basically, I think if you go looking for evidence that Twitter is helping people you disagree with, you'll find it, regardless of your political beliefs.
[1] No, not BLM/Antifa. It was an actual conspiracy theory with a token figurehead like "Q". I don't want to include too many details here because it seems like it died off, and I'd rather not help revive it.
Actually, replace "Russian" with "Russian, Chinese, Iranian, domestic political (both sides), or corporate submarine", and it's probably not that far from the truth...
It's amazing how fast millions of "legitimate" Twitter accounts of Korean teenager K-Pop fanatics all of a sudden become violently interested in suppressing non-Leftist-narrative hashtags.
Edit: Here's a url for a recent blatant use of a bot network (with Twitter obviously looking the other way). The same or similar networks were used throughout the election cycle, especially when there was any mention of election fraud.
