You people are thinking into this way too much. Parsing is punishable, not because people are harassing with it, but because ps3 players can't use them. ANYTHING that gives one player an advantage over another is illegal. So yes, it doesn't matter if you're harassing someone or not, making a single mention that you are running a parser risks you getting noticed by the GM team. Even someone in your own FC could report you. The best you can do is be as vague as possible when letting someone know they were underperforming.
