Here and here are just a couple of reports from a Russian human rights organization. Westerners will be inclined to dismiss it as propaganda because it's not a western "NGO", but this group backs up their claims pretty well, including with documents and victim testimonies.

And here is a bonus in case that wasn't bad enough. Completely unsurprisingly Ukraine also appears to be running Nazi-like medical experiments on prisoners...just like the Israelis, incidentally.

There's a lot of independent reporting on this if you just dig a little deeper beyond what the MSM is telling you. There were even articles in western publications prior to 2022 but i can't be bothered looking for them right now.

Since then of course they have gone into overdrive trying to sanitize Ukraine, but the mere fact that the MSM "fact checkers" are now in damage control mode trying to claim this isn't true only further confirms it.

Unfortunately the problem has only grown exponentially worse since 2022 as traffickers have way more opportunities to abduct and disappear people in the chaos of today's Ukraine, and there is a lot of money in this for the authorities.
