Those who give merits have their attribution criteria, we may not agree, but we have to respect them.
We absolutely do not.
Don't we have to respect the opinions of others, even when we don't share the same opinion?
I think that in a free forum like this, respecting different opinions is essential, so that everything continues to work well, as has happened over the last 15 years.
When I say respect, I don't say accept. Now, since there are no rules about how each person distributes their merits, each person chooses their criteria. And I, even though I don't agree with your criteria, respect your freedom to have them.
Who am I, to question your freedom of choice/decision?
Because there is this respect, we can be here to debate this subject.

It would be completely unfair to block an area of the forum from merits, harming users who make a clear effort to write good content for the community.
Its one thread -- one thread in one child board of one subsection of the entire forum.
You're just helping me!
Which makes it even more difficult, technically speaking, to make a topic not capable of receiving merit. I don't know if you know programming, but the way the software works would require major changes for this to be done. It's one thing to configure a board for this limitation, another is a specific topic.
Furthermore, this could set a dangerous precedent where whenever the subject of a topic was bothersome, the merits would be disabled. Someone is very dangerous that line of reasoning.
