Yup, comment, zero-width space, fixed. @MartinSleziak probably knows where to find the duplicate here on meta ;) — Daniel Fischer ♦ Jun 2 '15 at 19:18

@DanielFischer You can pick from the questions mentioned in this post. (Is this a new trend using me to find posts on meta?) — Martin Sleziak Jun 2 '15 at 19:23

@MartinSleziak You're just too good at finding things on meta, so it's simpler than searching oneself ;) — Daniel Fischer ♦ Jun 2 '15 at 19:24

I didn't sleep too well, so I upvote this as one more attempt to put the lazy askers and rep wh&%¤ answerers under control. Calculus is probably the worst offending tag here, but similar things happen in all high volume tags. But, did you search Meta? I think there already is a list of commonly asked questions. Martin Sleziak will find it faster than I ever could, so... — Jyrki Lahtonen ♦ Jun 1 '15 at 6:26
