You can ask questions to know about forum, but you have to maintain a limit, it is not polite to look into other people's pockets. There is no need to ask questions like how much money mods earn. No one will stop you if you ask questions, but you should have the thought to ask yourself what questions I am really asking. Your other question is fine anyone can ask this question out of interest, and you already have the appropriate answers from the community.
I remember a famous saying that "Do you ask a Man his Pay and Women her age" and i think OP should respect that.
This question has been in my mind for, like, more than 1 or 2 months, just after I joined this platform. And I never tried to find answers because I thought it was none of my business, but I was still excited to know about it. And today I have at least some of my answers. That are Yeah, Moderators do get paid (I thought they might have volunteered for the job for free; yeah, I know these are some childish thoughts). But your provided links also enhanced my knowledge, which I had never thought about before.
Well, it is obvious that moderators get pays as it is a full time job and who has time to do such work without any incentive? Also, there is a difference between doing the job voluntarily without getting paid as you can get relax a bit and doing the same thing with pay as then it becomes a responsibility.
