Here follow a list of all the reason an answer might be deleted
#The answer is a "try this solution...
... without (enough) explanation on why should one try the solution.
We require that answers provide some sort of explanation for why they are suggesting a solution. If an answer isn't properly backed-up, it will be deleted.
#The answer is a bad frame-challenge...
... who doesn't respect the premise of the question -> Don't give to OP a way to achieve what they want to achieve.
Even though a frame-challenge is okay, a bad one isn't. We require answers to respect the OP's request and answer the actual question asked.
#The answer is a duplicate of an older answer
Answer that doesn't add more than a previous older (at least one hour) answers are useless noise and should be deleted.
#The answer isn't about interpersonal skills
Answers that don't provide an interpersonal solution are off-topic here and should be deleted.
#The answer doesn't answer the question
Answers that are explaining a situation instead of giving a solution or are giving a solution to different problem should be deleted.
