If I had to guess at a moment's notice, I'd say some kind of spam/malicious content tripped some kind of automated trigger. Hopefully it can be fixed soon. Usenet unfortunately harkens back to the era before there were bad actors at all and thus has the same vulnerability to spam and other issues as email does. I bet it's something along those lines.
