Who the f**k is talking about technical blocking them… ???
You have your T&C, when you forbid them and get knowledge about multiaccounts, you can delete/restrict them… Its like every fucking LAW… I can smash someones car… Nobody will stop me, but when i get caught, i will feel the punishment… Because there is a LAW against it… But because your T&C are now allowed Multiaccounts… deal with it…
