Two of those posts are from accounts that are less than a month old.
One of them has a first post in /r/shadowban to see if the account is globally shadow banned or not. Also posting in /r/FreeKarma4U for similar reasons. Common for troll/bots.
One of them reposted an obviously fake post about wife having cancer. The original account that posted that story has been permanently suspended.
One of them hasn't posted since a week after they created their account, magically deleted some of their posts, and is now posting a year later with obviously fake karma farming stuff.
>None of these posts seem unreasonable.
Almost all of them are obviously fake or karma whoring.
>What exactly is the problem here?
There are obvious troll farms on reddit shaping narratives. We had a federal investigation and congressional hearings that confirmed this to be true.
I'd be willing to bet half or more of these accounts will be suspended at the end of the next presidential election.
