Wow, this gets crazier and crazier. So either any content provider should be able to determine within one hour whether every comment is "terrorist" or not (with guidelines as clear as "information which is used to incite and glorify the commission of terrorist offences") and remove it, or, more likely, they'd auto-remove every comment that anybody marked as "terrorist" and let people complain about it later. Coupled with law enforcement interface (which would probably mean notifying the law enforcement about somebody posting "terrorist content" - that's only make sense?) this paints a very scary picture for the future of online free speech in EU.
Obviously that's impossible and it'll be easier to just not have comments, which is exactly what websites will do, and exactly what the EU wants. The EU is sick and tired of people sharing their opinions and pointing out how stupid and draconian and bereaucratic the EU can be, so they did this to shut it all down under the guise of protecting copyright or somesuch.
