The EU plans
aggressive
censorship rules for "terrorist" postings.
Platforms that can't afford to hire people to work 24 hours a day to
carry out deletions would be wiped out immediately. And if they are
big enough to pay for that, they still won't be able to develop
automated filters.
The automated filters can't really understand what is "terrorist" and
what isn't, so they will be designed to err on the side of caution and
delete lots of other publications.
Well, if you delete everything, at least you can be sure you deleted
everything that is "terrorist".
