Be advised - insurance companies are watching what clients post on social media.  It has been reported that claims departments are checking claimant’s postings for evidence of possible fraud.  Many would say that is an invasion of privacy.  Many others would say that if fraud can be uncovered from a public forum, ultimately that results in lower insurance premiums for all.
But social media’s use by insurance companies’ may not end there.  Insurance Companies are looking for ways to use social media for underwriting purposes.  It is expected that within the next five years that methodology will have been developed that will identify certain risk factors and data that can be used in underwriting.  
They are not just looking at this information for personal lines, but for business as well.  They are looking at business postings for potential increased risks.  
Insurance companies are already using social media for marketing and claims.  Underwriting is the next natural progression.
