Quote from it:

On Sunday 16th March 2025 (the last day prior to the Act taking effect) I will delete the virtual servers hosting LFGSS and other communities, and effectively immediately end the approximately 300 small communities that I run, and the few large communities such as LFGSS.

For those of us that are not familiar with all the (future) online laws worldwide, based on what clauses will they be shutting down?

I skimmed the article, but couldn't find the specifics.
