CF could just sue LaLiga and the judge as interrupting and intercepting telecomms it's a really serious crime in Spain. Call the AEPD too because of consumers' right against both ISP and LaLiga's snooping. Another huge fine.
This is not an issue under the civil code (civilian issues), but something to be dealt under penal (criminal) code.
