I left a comment (as did several others) on this question. It deals with downloading music and copyright, both controversial subjects.
Looking at its revision history, I see it was closed, then re-opened by a moderator. Nearly all the comments are removed, not just mine.
Are comments routinely deleted when re-opening questions? Or, was there an issue with the particular comments left by myself and others?
Positive or negative feedback are welcome. I don't know if there was a problem with our comments that should be avoided in the future, or if it is standard practice to delete most comments when re-opening.
