I say no. It's already hard enough to catch hackers for it to be only 1 week per time caught hacking. After the 2nd time they've already proven that they don't care about the rules. That's when a long tempban or a permaban should happen. If they are major donors and they hack I think that they should maybe get a 3rd chance but I believe that that is enough.
With this suggestion I don't think their kits should be removed but just secretly make all their +kits into the regular and see how they like having to wait.
I would hate for a hacker to be caught and then hack again it would really annoy me. The punishment for hackers should be VERY severe as they as well as economical gains get on peoples nerves and I think that I would like to see this happen. If you make an example of someone hacking strip their sg kits, reset sg points and ban them in my opinion this would be spectacular this would discourage hackers and future hackers. +1
