Usage of /me/merges
Returns a record of merges that have occurred involving a user identified by an access_token.
This method allows you to take now invalid account ids and find what account they've become, or take currently valid account ids and find which ids were equivalent in the past.
This is most useful when confirming that an
account_id is in fact "new" to an application.
Account merges can happen for a wide range of reasons, applications should not make assumptions that merges have particular causes.
Note that accounts are managed at a network level, users on a site may be merged due to an account level merge but there is no guarantee that a merge has an effect on any particular site.
This method returns a list of account_merge.
