Tell you what OP, if you had spent some more time to create a more detailed and interesting opening post, I would probably have merited it. But I chose not to. Not because I am selfish, but because you didn't put much effort into it.
Everyone has the right to decide how to spend their merits. That's true for regular users as well as merit sources. You can always adjust the rules a bit to your liking. For example, in 99% of cases, I don't merit posts written by accounts who have collected many merits but have never awarded others with any. Regardless of what anyone says, I see them as not playing the game the way it's supposed to be played, so I don't see the need to merit them (most of the time).
I don't hate them. I won't ignore them and not talk to them. But I don't need to merit them.
I agree with you. If the op isn't bothered about his post getting merited, he would not have created it. Or is he just being a crusader or something? There's no absence of merits, just good posts, like this one you made, Op.
You don't expect these merit sources to give merits to posts that aren't worthy and as such it would seem like they are hoarders and even though there are those who board merits, I think it's their choice to do whatever they want with it.
Although it can be annoying when you make posts that deserves to be merited and you don't get but that shouldn't stop you from doing what you do because when you do your quality posts and it comes naturally to you, eventually the merits will come in because for me, it's as if these sources are checking how consistent one can be in making good posts, if it's not just a one time thing or occasional something.
