A friend of mine is having exactly the same problem, there's ALOT, and i mean ALOT of lvl 50 players farming D-webs,the worst part of it is that they insult you without reason,they start to annoy you with the Magitek mounts, they call ALL members of their FC to kill every Diremite etc...
There's 2 solutions,change the recipes for Weaver that ask for D-Webs,or,add more Diremite spawns in diferent areas.
