I don't think this is helpful to bots tbh. For over a decade every time I come across a clear bot account their comment history seems very human. I assume they're either buying real accounts for one-off astroturfing hit and runs in combination with deleting older astroturfing comments after the submission stops getting traffic to hide their footprints. Or more likely there's a giant ring of bots that submit innocent things and then comment preplanned innocent things in a giant bot circle and then make pointed comments on r/politics or whatever after establishing an innocent baseline. This is the obvious approach I'd take if it were me.

I'd also be really surprised if there wasn't coordination with Reddit employees/execs themselves for big advertisers.
