[2019] I was called a dickhead in a PE mission

I just joined a haz5 PE, and the aqrarqs were near the minehead. I instinctively helped them depositing all of them and I was called a dickhead for doing that and I was kicked out. I did not have time to respond.

It is the first time I have such a bad DRG expenience. Although I am very unhappy for that, I am not going to blame them for being toxic. I just want the know the reason leaving the aqrarqs near the minehead. Does PE's difficulty increase depends on how many aqrarqs deposited, or there are special reasons like swarm timing?

If there exists valid reasons, I consider it's myself to blame despite 70 hours of play time since update 10. If not, f*ck them.
