You may just put in your T&C that nobody from EU can use the site. No one will read it. No one will obey it. But it should be enough for lawyers to chase each other's tails in any case.
Perhaps. AFAIK click-through EULA's are not valid in most (all?) EU/European jurisdictions. Not sure about the presumably free blog -- but at least for things like eg: collecting personal data in an application/operating system (like Windows 10) -- you can't just pretend your users are at fault for clicking through a wall of legalese.
