Lol many of the professors with dog shit reviews both from RMP and in-house student reviews are still teaching at my school for like decades now. If they didn’t fire professors back in the day for being boring or talking a lot or being useless, I can’t imagine them doing it now due to RMP
It would be more worrying if this was “RateMyTeacher” because you’ll get a lot of “why don’t they teach us taxes?!” type students complaining and deranged parents complaining about rainbows and litter boxes. Teachers are usually not afforded the luxury of institutional protection.
I suppose one could abuse it with review bombing. I’ve never used it before so I don’t know how robust their authentication checks are. But other than that, it’s no different than having a bunch of kids complain during end of the semester surveys or spreading word of mouth. It’s just that with RMP, I can avoid wasting my time 80% of the time.
