If it helps, the description of the photo is explicitly misinformation. The photo is from a 2020 (businessinsider.com) lockdown (reuters.com) in the Izalco maximum security prison, halfway across the country from CECOT. The images depict Izalco inmates being stripped and searched for contraband in the yard, it is not a group cell. I do not know the toilet/shower/etc. situation of these men.
I'm not OK with the events the photo depicts either, but regardless it's not what is described in the ... meme, are we calling this a meme?
This is something I feel like Mbin does well. It shows separate up and downvote counts, so instead of a post like this just having a single score where 51 could either mean 51 upvotes and 0 downvotes or 101 upvotes and 50 downvotes, you can immediately see "Oh, a third of the people who voted on this thought it was bad, something must be up."
You can see this info in the Lemmy/PieFed interfaces (on desktop at least) by hovering the mouse over the point score, but the Mbin approach gives a lot more information to people who are just skimming.
This is why I've begun to sworn off learning anything about current events on social media. Everyone's posting propaganda, misleading pictures etc. If I want the news, I check news sites, not social media.
