I dunno why but I doubt this statement:

that was usually being done by Smartsteem taking the loss.

I'd like to believe that @smartsteem will deduct any accrued losses due of unvoting from the future payments to its delegators.

I remember once it deducted its losses to the degree of some cents or small fractions of it accrued over a period of about a year (that added up to a total of few SBDs and STEEMs) from the amount I sent it for promotion.
