It's not exactly MD that doesn't allow them to be posted. The groups who release the translation are the ones who first have this option; if they don't want it shared here, that's it. MD removes their tls because the group doesn't want to post on MD. If a group doesn't want their tl on MD, it is taken down, regardless of who uploads it.
Now if some other person/group tls it separately, that can be alright--there are even a few people/groups who are slowly going through and redoing (not just copy/pasting) new releases for some series which other groups took down. Other than some groups not allowing 'their content' on MD, MD also removes things that have official releases in a given language (or they plan to, sometimes things slip by for a while, etc.) as well as a few other (rare) reasons--rare enough I can't remember any off the top of my head....

That above should provide some of the info on why the chapters are being removed. If Krosth had posted chapters that were then removed, I would guess it's because they were thought to just be ripped off from JaiminisBox's releases.
Lymus' comment - "Krosth your scans look remarkably like Jaimini's box' ones."
Leads me to think that's likely why they would be removed. Uploading a tl of something that another group already tl'd (and removed or just never posted to MD) can be more.... difficult, as the translation will be close, if not the same since it's from the same source materials.
Anyway much more to be added to this topic, but this is already too long 🤣, and I think there may be like guidelines and whatnot that can clarify this much better than I can, in the forums.
