Flag system

That sounds like a good idea. You can report a problem and explain what happened to you, and your question will likely be unhidden.

I've been flagged once, and I really want to know what it's for. I want to be a good citizen on Khan Academy and delete what I did wrong so this website is safe, educational, and fun. I would hate to be considered a bad person just because I did something wrong that I didn't even know about. :(

@Jack, usually flags on your posts are pointless and nothing to worry about. If a guardian finds your post with those bad flags, they will remove them. :)
Just follow the guidelines and be friendly!

I once have been flagged for "Spamming" even though I had only asked 5 DIFFERENT people nicely for interviews. I was asking for interviews because I work for Alpha News. That is a team on Khan Academy that makes news about coding and KA. I just want to understand why other people say they can do interviews and not me. :(

Agreed with Jett, just follow the guidelines and you’ll be fine. I go through discussions and see many empty comments and posts that are completely unrelated to the topic. Some of those are just copying and pasting a word or phrase, and I flag them.

Coding Geek 21, is the Alpha News team on Khan Academy for people of all ages? 

I think my comment has been flagged, when I go to my profile page and scroll through my discussions, that particular comment isn't there. I haven't meant to say anything disrespectful or offensive at all. Do all flagged comments get deleted?
