That means the majority of this forum can't write meaningful posts, isn't it?
Correct. Out of more than 2 million accounts,
less than 1% has received 1 or more Merit points.
The majority of users are either spambots or bounty hunters/account farmers with dozens of accounts.
Why are they not banned then ? Is it because the forum needs them for some reason or another ?
I think it has to do with their large numbers. Many get banned, but many more get created. And real users shouldn't be banned as collateral damage, which means Mods can't just ban 99% of the users.
What I'm saying that in the hopes of getting a merit one cannot be normal, but rather spend an expensive amount of mental energy for number three in hopes that maybe they'll get a merit. And something that the majority of people will not be able to do. Due to lack of knowledge on most of the topics, particularly if they're new. Or because they simply do not have the IQ. Or not being a native English speaker.
You make it sound as if it is a bad thing that people who don't have knowledge on the subject they're "discussing" can't rank up.
