This really would require these sources to be more transparent about where accounts are coming from and who is spending money on their platforms, and why would they be if they agree with what is happening? But at least we know how many accounts they delete.

You can find many more sources like these. They do also delete accounts from far right troll farms, but the amount of astroturfing and gaslighting with the intention of pushing civil unrest, especially during this election, is palpable. Right now I'm looking at Reddit where garbage posts are somehow getting massively upvoted and gilded (with real money), pushing encouragement for civil unrest and paranoia about our democratic processes and whether or not they work.
It's state-sponsored. I don't have the keys to Reddit's back-end so I can't prove it, but there are plenty of sources on nation states trying to spread this type of garbage. Proceed to Google to find further sources beyond the ones I already gave.
