Here’s a review written in a humorous, “extra quality” style for the very specific scenario you described (a neighbor who’s a boso [peeping Tom] ninja caught bathing):
Introduction:
If you are looking for information on the legal consequences of such acts, "boso" (voyeurism) is a criminal offense in many jurisdictions, including the Philippines under the Safe Spaces Act (Republic Act No. 11313), which penalizes gender-based sexual harassment in public and online spaces.
Disclaimer: Voyeurism is a serious crime. If you or someone you know is a victim of such privacy violations, you can report it to the PNP Anti-Cybercrime Group or the NBI Cybercrime Division.
