Asking questions that are asked all the time in a sub or are already answered in the wiki. Not doing even basic searching for information before asking.
The only benefit to asking questions multiple times is that newer, possibly better solutions are recommended. I searched Reddit often for my questions and some posts worded questions better than others and some posts had wayyy better answers than others. People don’t go search previously asked questions so they can answer them. So I agree with you because it gets annoying after a time, but there is a benefit to having repeated questions asked. It’s difficult finding a balance for it.
I agree the balance is difficult and I agree asking later sometimes yields different results. My for instance about a sub and corresponding question asked endlessly is the privacy guides sub where people ask something like: "I'm using brave or firefox browser how do I be more private?"
Like my man you are on a discussion sub for a website literally full of instructions and recommendations with a link to that site pinned to the top of the sub. My goodness it can barely slap you in the face any harder.
It's not as bad as it was but the question is so vague that it almost demands follow up questions like what country, what threat model and what OS? It's not as bad anymore but it got super old and its the questions that are too general to be helpful and repeated hundreds of times over that really depressed me to read.
