民間企業ができないものは国がやるものだ。
テロ対策という意味ではそう。
実際にインターネット企業が行うのは、そうした特定のアカウントの削除、だろう。

Can internet companies monitor terrorists?
http://www.bbc.com/news/technology-30208602Big American tech firms, and in particular Facebook, are under pressure to become more active in the battle against terrorism. But what are their current arrangements?

Facebook is saying little apart from the fact that "we do not allow terrorist content on the site and take steps to prevent people from using our service for these purposes".

But privately the social networking giant believes it does more than most in keeping extremist material off the site and collaborating - where the law allows - with law enforcement agencies.

The company has links on every page allowing users to report anything that breaks the rules - from pornography to extremist material. There are four centres around the world, including one in Dublin covering Europe, where staff monitor the site and handle reports of abuse of its rules.

We are told that several "accounts" used by Michael Adebowale had been deleted by Facebook after being flagged as linked to terrorism. Now this raises some questions - users are not allowed to have multiple accounts so if there was a pattern of creating different profiles, using them for distributing terrorist content and then moving on, maybe that should have been a red flag.

If we are talking about pages or groups in which he was just one member, that may have been less cause for instant concern. And what is not clear is whether these deletions happened as part of an automated process or whether staff examined the content before making a decision.•••
