I can't speak for everyone in #bitcoin-assets, but I am very busy with my own projects, and I suspect the same is true for the users you called out in this post. Despite being so busy, we take the time to expose frauds and scammers. I don't know enough about this particular operation (bitcoinbourse), but judging by your reaction, I'm inclined to believe you are a scammer. You are using the exact same argument that the false teachers of Christianity use; that is, "you have nothing better to do then accuse others." Even if that were true, it shouldn't matter; exposing frauds is a valuable service, and these guys are providing it for free!
