Is it worth to open a quiz website?

I remember that in 2019- early 2020 everyone was talking about opening a quiz site.
Is it still worth it in 2021?
Some guy told me that it wont work anymore because the facebook/reddit groups are banning you immediately.
Is it true? I can work 6-7 hours a day for this project but i want to be sure it still works before i start it.

Yes it still works.
