It is the key point. If I get troubles, maybe crypto troubles or real-life troubles, then I fortunately see posts of someone in which I see point or points that I satisfy with, why not send them merits. Maybe, the point makes sense for me, and only at specific time in my life; but it does not make sense for anyone else.
I don't judge the post pinpointed above is a merit-abused one or not. It depends on each reader, and theymos don't care about merit abusements if not too extremely over-abusements.
