We can create a module which would enrich customers data in the background (avatar, contact details from social networks, etc) using https://www.voilanorbert.com/enrich/ enrichment service (this service charges 50 USD for 1000 enrichments per month) or https://en.dropcontact.io/pricing (23 USD for 1000 enrichments per month).
If anybody need such module please let us know here: https://github.com/freescout-helpdesk/freescout/issues/724
