Step 1: Follow the notification to the support dashboard. Just click on the notification when it appears in the notification bar, and you’ll arrive at the support dashboard.
Step 2: Go to your block list, and screenshot or copy somewhere, the names of everyone you have blocked on Facebook. If you don’t have anyone blocked, then this step is easier for you. People who have a lot of people blocked will have to spend more time doing this.
Step 3: Go back to the support dashboard and view the report. At the bottom of the report is a list of smileys, for you to rate how satisfied you are.
Click the “sad face” smiley (Meaning not happy) and a box will pop up, asking you to leave a feedback.
Step 4: In the box that pops up, type in these exact same words:
“I feel I am being harassed. I feel my personal profile is in jeopardy and I would like to block this person from me so I can use Facebook in peace”
And then submit it to Facebook. Copy-paste the text above if you have to. Using a variation of this or saying the same thing in different words might work, but I can’t assure you that it will. I’ve always used the exact same words and it worked out fine.
