I think it's will take then the Payout after 7 Days and convert it to SPS by using their LEODEX thingy - But how is that possible when claiming is a HIVE TX that needs only the "Posting-Auth" ?
Since Swapping will need the "Active Auth" and when it's done by the Leo Side of things then the Actual Payout must be distributed to INLEO instead to the User and INLEO needs to manage the Conversion (100% beneficiary)
In other Words said - People earning other Tokens rely on People needs to manually convert there INLEO/HIVE Rewards to their SPS/DASH Rewards? And manually Convert needs Active Auth.
Only for the LEO token... that gets issued differently. Hence can be "converted"
Its not using comments contract... its using a different method.
Will make sense with my comment to 2. question.
