Well, let me think about that. I left a comment on the Xocai person's blog, that said...

Oh dear, it's another MLM outfit. You are doing the tags wrong.

I was feeling helpful, you see, and they had left the commas out of the dozens of tags, so it was just one huge tag that nothing else would ever match unless an infinite number of monkeys typed for quite a while.

They changed my comment to this...

This is great please tell me more about it as I would like to start a business in my area...I have emailed you my details - thanks!

So, on that basis, I think we can see quite clearly whether or not it is a scam, don't you?

Update: You could also look at the web site of a guy whose main business is not selling chocolate, but who recommends a different brand.
