Do not let anyone mount pressure on you to tell you that you need to send merits to a user as a way of saying thanks. We don't really care for all these things because either way merits will come when someone finds value in what you write.

Newbies coming from the background of social media will always suggest things like facebook likes which I did also when I was a newbie. But when they grow into the system, they will understand that this system although is not close to perfect but is not also bad. By then, they will stop trying to suggest many changes to the forum.
For Christ's sake, this is not a normal social media platform or any other forum that will enable the "Thanks/Likes" button as he wanted. And since he is not the first or the last to register here, he must admit and obey the rules of the forum. Peradventure he can't obey it, there is nothing wrong in excusing himself from the forum if our deeds don't tally with his. That is civil enough.
