Tested T-Mobile to and from Verizon. Gateway Pundit and links from here are blocked going into T-Mobile and coming out from T-Mobile. T-Mobile to T-Mobile also fails as you would expect.
Like I said, I think they may be doing it through their proprietary text messaging SMS apps. My wife and I are using an obscure third party texting app and having no problems. Texting apps from T-Mobile, Sprint, Samsung, Google, etc may all be updated to censor whatever they don't want people to see. Try some third party apps and see if it makes a difference.

IDK what else is being blocked.

I use a 3rd party app already...
