Have you considered changing the "First Language" profile field to "Native Language"? There's been a huge increase in the number of obviously non-native English speakers who write "English", perhaps under the misapprehension that that's the first foreign language they are learning; or just as likely they have emigrated to US from Asia, and say their first language is now "English".
This leads to problems with interpreting questions (Why on earth are you asking a question like that if you're a native English speaker?).
In many cases, it would be far easier to give a useful answer if one knew the person's L1.
Of course, no one is obliged to give that information (on this site) and can write whatever nonsense they like. (A note on why their native language is important would be useful too).
I think the question is ambiguous and should be changed; or a note added ("if you speak another language better than English, please put this language").
Thank you for considering this matter, which is causing annoyances at the coalface.
Red's away at the moment, but if it can be changed, it should be a relatively simple matter, so when he gets back, we can try it.
