Don't worry RandomNuub, all the crying happening is a sign that there are actually admins doing their jobs.
Perpetrators got too used to the hibernation of the admin base in EU, with the special weight on Siege mode, and thought they could get away with it forever.
As one of the replies says, sure you can fix stuff instead of banning people, but with my vast experience on this field I can say with sure that, who has the mindset to do this sort of actions and behavior once, will always be volatile enough to do any other action like these ones in the future.
I'd rather play with half server only than with a server full where 50% are scum with the only propose of ruining the rests game time quality. But this is what I feel, obviously can't be taken into such an extreme proportion but into consideration while balancing things. Everyone deserves a second chance, and no one should need to ask for a third.
Just keep up the good work (aka the work of several admins by one), and specially keep in touch with the community like this, secrecy isn't good for any community in any place in the world.
