I use voyager app, unsure about other apps or website, but check if your able to easily block users. Instances and communities, I usually scroll through the all free and block things I just can’t stand and are heavily just annoying, also has a ability to filter out keyword.

Low IQ is a type of singling people out who are not what society wants people to be. A form of subtle eugenics, make the “dumb” people not be able to do things because a “test” says there IQ is low, for instance someone who speaks another language could mis understand the “test” and people think there idiots when in fact they just wasn’t good at English. This also goes for people who are absolutely horrible at English reading and comprehension of “tests” when they could be brilliant in other aspects of life.

So remember there is no way to “test” how smart or dumb someone is.
