It isn't your place to be doling out advice to anyone.
People come on to a public forum and ask for advice. Everyone brings their own views to the table and the OP can take it or leave it. That's the idea of a discussion forum. Clearly we won't all agree on everything, and sometimes things come across not quite how they were originally intended. But, nevertheless, I don't think it's anyone's place to say who can and can't offer advice/info to anyone else.
