Very interesting, You received one Merit till now and given one merit .(Interestingly you given/received merit from same user within the interval of 10 minutes).  Same is true for the user to whom you have given the merit. (Might be you both are merit abuser).

Now coming to your suggestion then you need to understand below lines clearly.
Merit is not a right but a privilege that is getting driven by good quality/useful posts.
(Altough there are some merit abuse but in the end merit of these abuser will exhaust)
