There are quite big disinformation about SONM project here on btctalk for sure. I don't think its scam or scammy. And I don't think it will do 5x that easy. It will be better after more updates and these "oh scam!" cries.
I've seen a lot of fud but can't seem to get any real answers, maybe its competitiors or people trying to keep the price down to accumulate, can't figure it out.
