"They" are actually getting marginally faster over time. I am going to make an educated guess that their post frequency will continue to escalate the closer we get to the election. I'll leave it open for speculation why that might be so my comment doesn't get scrubbed...
They're obviously not being paid. A paid campaign would have metrics and would have already abandoned this dumb shit with zero odds of influencing anyone.
At the start I wouldn't have been able to tell you if they were a MAGA or a useful idiot. After having everything explained to them over and over, I'm more convinced on them being a MAGA cosplaying as whatever they're doing here.
Also a peevish child delighting in any attention, even negative.
