I found out some disturbing news regarding an active provider on here. She is a well known provider who changed her name this year. From what I was told it was because of family issues but I found out otherwise today through a mutual friend he got in some trouble because of her. After some Google search and screenshots of text messages i found it to be true. She has been involved with authorities in help getting people busted to get out of other police matters she was involved in.  

I am NOT putting  her name out there but how do you let people know of what is happening. She's dangerous.  

What should i do. How does one handle a situation like this other than staying away from her and how to to let other know safely without retaliation.
