The blog under the name blog.messainlatino.it had been unavailable since Saturday morning.
A message from the platform operator Google appeared on the site, stating without further explanation: "Blog has been removed".
The block applies to Italy and Germany, among other countries.
The page also links to Google's "Content Guidelines", which specify which content is prohibited on the platform.
Under the keyword "hate speech", it states: "Hate speech is prohibited. This is content that promotes or condones violence against individuals or groups based on skin colour or ethnicity, religion, disability, age, nationality, veteran status, sexual orientation, gender, gender identity or other characteristics associated with systematic discrimination or exclusion, or content whose primary purpose is to incite hatred in relation to these characteristics."
On the now blocked page, supporters of the old Latin Mass had been campaigning since 2007 for this form of worship to be allowed again without restrictions in the Catholic Church.
At the same time, they criticised the defenders of the new form of Mass, which has been customary in the Catholic Church since 1970, sometimes harshly.
They also sharply criticised the opening of Catholic moral teaching with regard to same-sex relationships and recalled the Catholic doctrine according to which homosexual acts are classified as sin.
Ultra-conservative content providers
According to its own information, the site recorded more than one million visits in June alone.
Partly due to speculation about Pope Leo XIV (elected on 8 May 2025) allowing the Old Mass to be celebrated more widely, traditionalist and ultra-conservative content providers on the internet are currently experiencing considerable growth again.
The editor-in-chief of the blocked blog, publicist Luigi Casalini, announced legal action against Google on the X platform.
Among other things, he invoked Article 21 of the Italian constitution, which prohibits the suppression of freedom of thought and expression.
