I have seen multiple posts and threads on the forums where I felt some people were in need of help or counseling or even where I feared they were in danger. Now as much as I want to help them, I feel like I am not equipped to do so and always fear I will make things worse. So I rarely reply.
The main site has a Report button where you can flag the user or post:
If you come across a user who you fear is in danger, either by threat of abuse, suicide, depression, cyberbullying, or self-harm, we ask that you please report it to us immediately. Reports can be made by clicking the REPORT button on the content post
Could we have a flag in the forums for the same things? So maybe ambassadors could link to appropriate resources and help the person? I feel like leaving it to the users is a disaster waiting to happen.
