I don't know how much the difference between "blocking" and "restricting comments" goes, but I do remember Trump wasn't allowed to block twitter followers/commenters as POTUS because his account was part of "the state" (SCOTUS ruled on this, I believe). I would image the same would apply here, given MSU is a public university. Again, I'm not sure if limiting replies is the same as "censorship", but it's definitely worth getting to the bottom of.

Regardless, though, this is ****ing weaksauce from whoever runs that twitter account. Own it. And restricting replies will only confirm people's concerns, so obviously the strategy here is flawed as hell.
