The simple fact is the problem is freedom.
Just look at PvE people have a few hundred worthless Dino's just because they can and a base on a massive scale just because they can and yet another problem also caused by people with too much freedom is pillar spamming sometimes all you need to fix the problem is a iron fist add restrictions that will fix the lag and various other problems.
And PvP just add mass kill zones in the scenery who cares if it kills Dino's on the surface people aka cancer have been without consequences for too long maybe this will get the job done.
Or on a serious note add a few cubes in the scenery that store the player id when they come in contact and that will raise a flag to indicate further investigation then let the ban hammer loose I mean I personally prefer the iron fist method but there is plenty other methods
