Why do some Blurt It members on here not answer the question given to them but end up saying something else?

Sometimes the question that the author thinks s/he is writing is different from the question the responder thinks s/he is reading. We often don't find out relevant details until comments are posted on the answers given.

Sometimes, the question is so outlandish taken at face value that it can only be considered a joke. Thus responses may seem inappropriate to the person asking the question.

Sometimes the question is one of a series of questions all in the same vein, so the respondent tends to read into the question more (or different) context than may have been intended.

Some questions are of the nature of "have you stopped beating your spouse?" That is, there is no good way to answer the question asked. One can only reasonably answer a different question or make a comment.

Some respondents have an agenda of their own that they post regardless of the question asked.

Huh that questions makes no sense

First option they don't found the question and the last option don't know the answer properly.

Well first of all we all have another background and a way we look at things
sometimes they don't know what you really mean by your question or they're not theirselfs at that moment, that's why they answer you different then asked
