For those who say it's a scam, what's the benefit of the scammer exactly?
Well, you know, there are quite some weirdos in this world. Not here to judge, but some people have fun in strange things.
There are some people now already involved in this thread and I for myself enjoy the valuable contribution of some of you providing good links very much for details I forgot or never knew. Many thanks, greatly appreciated!
As chances are slim, I will skip to waste energy for password crunching as there are too many red flags in my opinion.
