Brother, Adremus smeels like rubbish, there is money involved:

Adremus try to sell a promotion in the main page , Obviously is some kind of fraud.
But I dont understand why do you insist on assume Universtal Talents is a crap or scam if it is no cost involved. Universal Talents have a roster, is like a talent pool. Worldwide. Is like the Uber or Airbnb concept but for music bookings. For example If I m a event manager from Miami and I need a rapper for some event/gig I use the searcher and I found some results like:
http://universaltalents.com/artist.php?stoppa
I think is just... one more music platform like others: Last.fm, Reverbnation, Bandcamp... There are platforms more focused on Promo or gain visibility and others more focused on shedulle events, get gigs, connect artists...
My experience is good for now. I use Universal Talents to find Singers to cooperate in some projects (For a producer is hard to find orginal and no copyright acapellas)
