So-called "Lesley" appears to be a bot, because they're oblivious to the context (it thinks you're posting to them, despite it being an auto-follow). The CGI image is a classic tip-off of an AI/bot account used by shills. The group attack is likely other bots joining in.
The trick to exposing them is to use disjointed unnatural social syntax until the bot handler turns up (but you have to be careful to phrase it in such a way you don't appear crazy).
Third personing works nicely: 'Observe as the broken bot cannot comprehend who is replying to who. Democrats using bots?'
The bots aren't generally programmed to handle bot comments, ironically, and if they do, they often do a bad job. 'Banana, cheese, jam: identify which isn't a food?' - unsolvable question for a bot.
