I think many will face this soon and will distribute as much merit as physically they can, and not as much as necessary. Nobody asks merit source to distribute the entire bank. I also assume that the number of sending so-called merit bombs will increase (50 merit per 1 transaction) And although there are many opponents of such methods for evaluating posts, and some may say that this merit abuse, but theymos says that it is better to send 50 merit even to a not very useful post than to allow your unspent merit to be burned.
