If copyright-protected works are included into my posts automatically by social media platforms, am I responsible for this and is this a copyright infringement? What if I link to them or embed them in my own website or blog?

Irish law in relation to copyright infringement is found in the CRRA 2000. There are no special provisions relating to social media, but posting or reposting of works owned by others must respect ordinary law. Linking alone, however, is likely to be lawful as Irish courts apply the rules developed by EU institutions. However, internet service provider (ISP) liability rules and the awarding of injunctions to disable subscriber access to ISP services are regulated under Statutory Instrument No 59/2012, as well as ISP/rights holder graduated response agreements, which may ultimately lead to an ISP terminating subscriber access to services.
