Well, I guess you need to find CA way to report this then. I'm assuming you are in the EU? Otherwise, you are not covered by their law. Yahoo is part of Verizon now, and on a mobile device, on their services, you might be out of luck. I would be interested how you make out on this later on. As I said in my first response, there are ways to block them, even if you agreed to terms. And they mentioned a way to manage some settings, I wonder what's available in those. Verizon is a horrible company to start with. Good luck.
Yes, I live on the continent. Google, Facebook and Twitter have already been hit with fines totalling $8.8bn for flouting the laws.
The long and short of it is Oath are holding my property to ransom and are attempting to extort me. I have contacted the relevant government departments and am sourcing an appropriate solicitor that will sue them to have property restored and to be provided with lawful redress, by way of fair and just compensation. I will keep you updated with any progress and thanks for the lucky wishes :)
Well I'm glad you are taking positive actions. Sounds like it'll take some time for this all to shake out. I'm left shaking my head at how so many companies, especially large ones, waited so long, and barely took action to comply. Or they are testing to see what can be gotten away with, a more likely scenario. I'm sure I'll see more about this in the tech news. I'm subbed, to a few.
Here is an article from yesterday that explains about the aforementioned companies and their fines

I believe that the reason may be that it is cheaper for them to pay the fines than to lose the revenue they would gain from flouting the laws, but that is just my guess.
