Fact is that when people post a topic for Merits than it counts in spam. And if anyone post a topic or comment to a topic to help others or to give knowledge to others than definitely the post Merited by the members ( I am saying after eyeing many posts).
You are posting for merits but it counts as a spam? How on Earth? I think if you main goal is to get merits then of course you will give your very best on that post, isn't it? Thus your post got a lesser possibility to be called as a spam (unless you come to the point of begging). I can't understand, am I missing some points? Please enlighten me.
Anyway, I love the concern you are showing as well as the initiative to remind them but IMO it is not necessary in the first place. What seems here is that you are trying to spoonfeed them, hmm sort of tolerating their laziness. I mean, those threads are not too hard to find and lots of versions of it are scattered all around the forum so it's impossible that they don't even have a glimpse of it. If they don't like to read then it's not our problem anymore. Just let them deal with the consequences once they made a mistake.
