First of all, you do not have proof of vitx even dying in the first place. So from the video it does not show vitx breaking nlr. But it does show that vitx did nothing about his buddy "cocaine" who was breaking nlr, maybe he warned him after but that's still not an excuse. And yes, you did camp in there after you killed everyone, which is not allowed.
as Zax said
5.2 Finish - You should leave the base as soon as possible when you have finished raiding.If there is things growing you cant wait for them to finish but you can take them.
And for beaver's argument, the 5 min thing is for how long a raid can last, but since 5.2 says that after you finished raiding, you should leave as fast as possible, it makes beaver's argument invalid.
