Well Xaurum Slovenia (Slovenija) utilizes same team members that participated in Karatbars agenda. Nothing wrong with that though (nothing like dedicated hustlers I suppose).
But there is something that I find quite ridiculous. If this is something that is gaining international attention, why are there still mainly Slovenians in "Xaurum fans FB page". And why using facebook page "Xaurum official" that has fake likes? Yes I will said it again. FAKE LIKES. Is this your marketing strategy, I mean come on!

If the likes are a measure for you to buy Xaurums then don't buy them. If you think that facebook is reliable to get an reliable information, then don't buy the Xaurums.
I suggest you to wait one year in the middle time you can monitoring whats going on and then you can decide again if you will see that can be profitable for you.
