infact if theymos most do that i wouldn't mind suggesting him to increase those who their allocations are very small and then remove those who are not active on the forum for about 3-8 plus.
They do not need to remove merit source to increase the allocation of other merit source, it is better to have more merit source instead.
What is the usefulness of the merit source who has been absent from the forum for 3-8 months? Perhaps you didn't read that.
And if at all such comes back and is still willing to be a merit source, he should reapply, in my opinion. It's now left for theymos to decide if he is still worthy.
