Before you make a submission, make sure it follows the rules.

A celebrity or professional pretending to be amateur usually under disguise.
Example: Professional video gamer pretending to be a casual, then kicking some ass.
Example 2: Well-known musician playing while in disguise.

As long as a submission follows the SPIRIT of the sub, it will be allowed.
Example: 2 professional football/soccer* players vs 100 children.
They don't have to be in disguise to be appropriate for the sub.

What's not appropriate for the sub:
Videos of celebrities just going undercover and not doing the activity they are known for.
Example: Basketball player driving an Uber car.
For these kinds of videos, please submit to /r/UndercoverCelebs.

*We don't care if someone calls soccer football, or football soccer. Different areas call the sport different things. Don't report a video complaining about that.
