"Maybe, but you should still block them as they are breaking the law, especially if they are, as ValiantSoldier hypothesised, a troll." (emphasis mine)

They're not breaking laws for being underage, nor for trolling.

As for the UK law, that primarily goes against cyber-bullying. That's trolling of a whole other level. Also, that press release offers little conctrete information, just reactionary sound bites. Has anyone been convicted yet? Does this apply to British trolls or British troll victims? Either way, its jurisdiction ends at the Channel.
