CMU has published before that probably Russian adversaries fused different groups in the social graph of Facebook in 2016 and basically got in control of both groups after the merge. Bots are used to get attention, steer the conversation, introduce key retweeters to bot retweeters and merge a couple independent user groups at scale. This is a highly specialist job not a couple of random amateurs, and could be the underlying mechanism at work here. Big brands pay a fortune to execute similar tactics but are not even 10% as effective. Coke for example has an annual advertisement budget 7+ billion.
