I don't think there are any rules that we cannot discuss merits often.
There's no problem with discussing anything here. From bitcoin to shitcoin & Elon Musk to surgical mask
but you are not allowed to create repetitive threads again & again & again. Users more frequent in meta are very familiar with this type of thread & AFAIK, there was a compilation of threads on "Merit" just because someone was too bored. I can't remember when I last saw a thread as of this one; in fact, I can't remember if I have seen even. But, I'm sure there were a few threads as of this one. That's why some see this as a repetitive thread & one more merit thread LOL.
