Does Crowd Social Signals Help Improve A Domain’s Trust Level?

In the 95th episode of Semantic Mastery's weekly Hump Day Hangouts, one participant asked if Crowd Social Signals can help improve the trust level of a domain.
The exact question was:
Hi Guys,
Good day. Quick question. Have you come across Crowd Social Signals? It claims drip-feed by real people.
Does it helps to improve the trust level of the domain?
Thanks.
