Some of the neighbors set up a decloaking bubble of drones around one of their systems gates. The other gate is to large to do this with. The drones are in a complete circle that flares out in general range of a ship jumping into the system.
Spam or just intelligent use of game mechanics? Some have said that it is causing a bit of lag when they are loading into the system. These types of things are sometimes done to also lag people. CCP does not like their systems being lagged out by player's dropping objects. Having jumped through this swarm a couple of times it does make my overview hiccup all over the place.
The question is, "is this a ridiculous number of drones or not?"
Even as I write this, I jumped into it. I was in an interceptor and the small size of my ship was the only reason I did not decloak. I was but 2024 meters off the nearest drone and a hurricane was sitting on the gate ready to try to grab me.
However, interceptor for the win. I was in warp before he did anything. I will say that I am used to jumping into a system and taking stock of a situation. With this set up I'd be decloaked before I got my feet under me just due to my natural cautious habits.
An interesting situation.
