Report Abuse. People can delete their facebook for any reason. It could be because they don't want their future employer to see what's on there, they could be tired of all the changes facebook keeps making, or maybe they just don't want to connect with the people on there.The answer depends on the person.ome people delete and make a new one so they can start new, and not add the friends that they don't want. I knew a girl who deleted hers but made a new one so she didn't have to have her parents on it. There are many reasons why people delete their Facebooks.
