Most bots reply in under a second, so I think I have it set Where if an npub replies to a post within a second or two, it's probably not an actual human, so it drops the post.

you'll need to make that based on the time between receiving rather than the timestamps or the bots will send them in a second with 5 seconds later on the timestamp and same problem again
Oooohh That's probably it.
self declared timestamps are always lies, and so many algorithms tolerate quite wide variance, you need a time skew detection to really get that right which is a several seconds long process of sending timestamps back and forward until you get a stable average
the verge cryptocurrency ran into a huge problem that enabled the first real world timewarp attack due to a network time consensus
i'm pretty sure satoshi said something about how timestamps can't be trusted but you also have to draw a line somewhere, i think bitcoin block timestamps are allowed to be as much as an hour out of order, but legit timestamps should really never vary more than about 12 seconds
