How do you know if your video is flagged? Please Read

Does this mean i got flagged? I logged into youtube also and went to my videos and i saw under my video it said "Rejected (content inappropriate)" im guessing i did get flagged because i had 500 views and next day i got this email. Let me know what you guys think.

i also got a email from youtube saying:

Ye you got flagged. I got one of those when my account got flagged tooo.

you really don't know its kind of a hit and miss with youtube.

ive had a sexy video up there for 3 mths with about 30k natural views then got one of those messages too. I knew some bible pusher or half-wit had flagged my sh1t

So does youtube really check if the video is really inappropriate? or they just look at the flags it got and remove the video?
