I've found a lot of links from other forums where Proper75 is acting. Since these are all in german, it's easly the same seller.
Someone who speaks and write in german, must write in these forum regarding the danger!!!!

He writes in german. But there is a Proper75 who writes in Cyrillic (I think it's cyrillic) that lives in Israel:

I hope these links don't conflict with forum rules. This is for a good cause!
