Yoshida's off the cuff remarks on parsers amount to "Use them, but don't be a dick to others about it". The whole "saying parser gets u banned!!!!" scare was always vastly exaggerated. The person in question was punished not for parsing, but for 1) harassing someone with parser data 2) lying to a GM about it. And they weren't even banned. It was a suspension that got downgraded to a warning. As long as the people you parse with regularly are friends (a static, an FC) and you don't mention it to other people and/or harass people over it, you're entirely fine.
