TLDR: A group operating in the darknet was busted after a long investigation. Besides Cocaine and Heroine (thats the only strange thing about it - he does not sell H to my knowledge) 20 kilo of extasy tablets and 90 kilos of "other synthetic drugs" were found.
He was the only german vendor that currently pushes blue party masks in big volume. Since LE knows about his dealings I put the name out. Stay safe and do not order in the following days.
Thank you for posting a tl dr. I was reading it for like 20 minutes then realised it wasn't in English
