But I don't know, if you feel sorry for him you can send him a little merit, we also can't make a problem of that because the forum don't directly moderate the merit system.
While the merit system is not directly moderated, you should consider spending your sMerit on posts that are truly worthy. This means you shouldn't spend your merit on useless posts that are likely to be questioned. That's how the merit system works, but if you get good quality posts from anyone then you can do it any time.
Basically the merit system was introduced to encourage higher quality, so if you find a quality post, you can get it regardless of the rank. So there's no reason to care to some one without good quality posts, that way you'll avoid abusing the system.
Of course spending sMerit on useless posts will raise suspicion, possibly damaging the account reputation. Generous people will not spend their sMerit carelessly, they are more selective in choosing posts that are really worth helping and as an appreciation for contributions to the forum.
I've done it here before, spending Merit on quality posts while helping them get closer to a new rank. My success in being promoted to Sr member rank some time ago thanks to the help of generous people, it is very appropriate for me to help other users like they did to me.
