Slovenian ISP T-2.net also violates local network neutrality laws here by requiring customers to pay extra to unblock some special TCP ports, like 25 and 53, meaning they block selfhosting email and dns servers without additional payment. I filed a complaint to the national regulator AKOS. They first responded with agreeing with me, but nothing was fixed for many months, and upon emailing the regulator again, I received a different response from another employee claiming that charging more for unblocking special applications is legal (it's not).
