There are a few ways to go about filing a complaint with the appropriate platform or authority. Here's a general guide: 1. Contact CSC's customer care team: CSC is a Canadian platform that offers a variety of services, including online harassment reporting. If you have an issue with Facebook, then you can reach out to their Help Center or use the reporting feature on the website. 2. Use online harassment complaint platforms: There are many online harassment complaint platforms available, such as the Cybersecurity Response Centre (CSC) and Facebook. As long as the platform offers equal services and is tailored to your needs, then it should work just fine. It's important to research which one is best suited for your needs before filing a report. 3. File a report with authorities: There may be certain authorities that you can file a complaint with, such as law enforcement or social media platforms' parent companies. It's important to do your research first so that you know which authority to contact and proceed from there.
