That will be about as effective as attempts to block soccer streams in Spain are, and I don't think it'll pan out as a viable solution without worldwide enforcement backed by BGP bans of providers that continue to host non-compliant sites after notified. It's technically possible to consider a future where RIPE might withdraw your BGP assignment if you host advertising malware on your website, but ultimately that's just as dystopic as the DMCA is today, only scaled up to worldwide impacts and drama.
