the esporx user is a bot that just posts links all day every day to thousands of "subs"

Many such cases.

the throwaway account was made 4 years ago makes the odd post about some tech related thing (buying ram chips) with multiple months between posts

To be fair, sounds like my Reddit account...

...and then it has suddenly decided to be very anti tariff

...if I'd sold it or gotten it hacked at some point.

I get irregularly posting. At this point I basically use Reddit for tracking video game sales, and rarely comment. Out of curiosity, I checked: One week, two months, four months, five months, six, eight, ten, etc. EDIT: Hahaha, my first page goes back two years.

But if you suddenly change and get more political in one direction, that means that account was scooped up by some actor to push an agenda.

going through the comments some of these users do not appear to have posted in gamers nexus before...

That's not always malicious, but generally means they got some link from an outside source, yeah.

This is botting and brigading.

...is there a way to see a breakdown of a users post history by sub?

I think so, but I'm not familiar enough with it to pull that off the top of my head. Search it out if you're invested, I think I remember there being some way to pull that data.
