Karma? Why?!

I'm not very active on the internet and prefer to stay in the background. Every now and then, however, I have a concern that requires at least a little human interaction. And when I have a question that no one around me can answer, the response is almost always, “Ask on Reddit.”

And when I do, I always face the same problem. “You don't have enough karma...”

What does Reddit expect? Am I supposed to write a hundred fake posts with some bullshit every day just to get karma? I just have one question, why do I have to litter the internet for that?

I don't even understand how this karma system is supposed to work.

“You don't have enough karma, but I'm not telling you how much you need!”

Why? It's like wanting to buy something in a store, but no one there will tell me how much it costs, only that I don't have enough money...

Maybe this post will earn me a little bit of that stuff, maybe it will be deleted, I don't know, I really don't understand this platform. -.-
