I found a game that seems inappropriate or might not even be a game. What should I do?

In the "contribute" section under each game, there’s an option to flag the game as inappropriate. Flagging games will alert the Kongregate staff that something is amiss.

Please do not harass the developer or leave vengeful comments for the game; your anger is probably better spent elsewhere. If a game is broken or not working, game bug reports are preferred to flagging.
