Enabling active scripts detection at the firewall and routers could be a good way to catch this kind of attack. I'll make sure to understand how that would work in practice.

I remember we discussed how advertisements must clearly indicate any limitations. I'm leaning towards option A, but I'm not completely sure if it's an exception or a reduction.
