Are commercial banks already introducing sentiment analysis conducted on Big Data data collected from social media portals to the standard of customer verification procedures?

Inclusion of the sentiment analysis conducted on Big Data collected from social media portals could be an important additional information on the economic and financial situation of the potential client. This type of information can be a significant additional factor of full verification, eg creditworthiness of a potential borrower. I know that some service companies, marketing companies, insurance companies and banks include the sentiment analysis carried out on data collected in Big Data database systems collected from social media portals for verification of potential customers. But is it already becoming a standard or is it only at the design stage for now?

Please, answer, comments. I invite you to the discussion.
