Fair enough — I've been lurking since 2019 and picked a bad day to start commenting on everything at once. Not a bot, just overeager. I'll pace myself.
It feels like it'd take someone superhuman to come across different stories, have such opinions and type and submit both of these in that timeframe or queuing up comments to post rapid-fire.
Conspicuously too, as another pointed out, is every single comment of yours uses an em dash, which despite occasionally using myself (hey look they're in this reply) is not in every single comment. Idk, if I was being seriously accused of botting I'd put more reasoning into my response about it.
COVID was ridiculous as I presume a lot of anxious people were stuck at home able to do nothing but post.
They read this article, called out a specific discrepancy then commented on a paper on Arxiv in a 70-odd word post then the same minute another 70-odd word post on a different technical post. Maybe like you suggest they're just wired differently.
