I tried fully deleting my Facebook account multiple times about 5 years ago. Each time, it became clear that my information was never leaving. Friends were still able to pull up my account. My credentials were still being recognized and allowing me to login to an account I was told was now nonexistent.
Now I see my phone number was part of the breach. I am so fed up with Facebook.
