It has been debated on this site what does and doesn't constitute "legal advice", most users work off of the argument that answers on LSE are not legally considered "Legal advice".
Legal advice that is not given "as a business" and where its author does not falsely purport to be licensed to practice law in the jurisdiction at issue is not illegal.
Although it's legal to answer questions on this site without the fear of being sued, it's hard to deny how uncomfortable it can be to answer questions that include:
"Do I have grounds to sue"
"My family member is sitting in jail, what should I do"
"I'm in a bad situation with the law, what should I do"
"Am I liable for (Y), if I did (X)"
There's a really good case for not answering this type of question, for fear that the person might actually take the answers at face value, and act on them without doing more research. It would be understandable if personal questions were a fringe subsection of questions, but they seem to make up a majority of the questions.
LSE already has a feature that applies to the title, which won't let you post if the question is "too subjective", should this feature be applied to the body of the question?
