As we know only way to have more merits is to give it away.
The only way to earn merits is to create useful posts. However, each user may understand usefulness differently.
1) Why? I earned it in hard way.
I'd never add this as an argument of why I don't merit newbies, despite the fact that I
do merit those. Even if you'd earnt them in a hard way, the merit count won't be reduced from your account. The only meter that gets reduced is your sMerit count which is useless by itself.
The purpose of the merit system is to merit.
2) Merits are valuable, I can't give it away to unknown?
They aren't valuable. They are units that must be circulated among the forum. Again, you keep merits, you give away sMerits.
First you should know, you are getting in return things you can't see or think, you will never get it while dealing with known. People giveaway their whole wealth in search of it and you're getting it through merits I don't think this is not a smart deal?
There's no reason to say all that. Just say that if you merit newbies, you encourage them to continue making quality content.
