They didn't get banned. They got an email from CF support saying that they cannot cache TXT files and that they'd need to disable the proxy.
This does not mean banned.

They didn’t ban the whole organization, but effectively told them to stop. I don’t see a difference.
CF didn't do this. They sent them an email telling them that what they were doing was a violation of their TOS and to cease doing it. They did not kill off their account. They still have the option to comply and continue with CF, which seems to be what they are going to do at the moment.
Hopefully, CF will grant them amnesty on this one. At the end of the day, an HTML file is just a text file, so I don't see why this would have even mattered to begin with.
