After verifying a few postings in the group "USA Business opportunity Marketing" by using scamadviser.com and the Open Source product Adguard for scam warnings, I got the following message from Johan V. Caem:
Johan V. Caem: I permanently banned you from the group "USA Business Opportunity Marketing" since you mentioned that our members are promoting scams. As long as a company pays it isn't a scam yet. I am the scam controller and I delete anyone who promotes a scam. Leave your colleagues alone, respect eachothers posts. If it is really a scam I permanently delete them, and I have the knowledge to decide over that. Enjoy your marketing experience Rudolf, just not in my group
Rudolf Faix: There is only SCAM!!!
Johan V. Caem: you should do some personal development on your brain Rudolf, like I said I have the knowledge to decide, you try to take it from a website
enjoy your day
It seems for me that Johan V. Caem does not know what is a complaint and a negative report at the web or he is the boss of the scammers there. Google lists a lot of such complaints!
I did not find one real business during the short time I have been visiting the group "USA Business opportunity Marketing".
