is what he did actually enough to file charges against him?
I don't think you understand how things like this are handled, and to be fair I don't know how they're handled in Denmark either.
In the US, if you file a complaint with the FBI office and you supply them with enough evidence of an attack, the FBI contacts the ISP and informs them that someone is DDoSing with their service. The ISP will then contact the DDoSer and suspend their service until the issue is resolved. They could also just outright blacklist them and cancel their service altogether. Usually the actual police won't get involved unless money or credit card information was stolen, or the person is making death threats.
wait what?
i though that canto xe and okiver were the same person.
No I can say with 100% certainty that they are two different people.
