Facebook has set up some rules and regulations and terms and conditions that have to be followed if you are a user of the platform. Moreover, not following the rules can have several consequences both minor and major, that can ultimately result in a locked Facebook profile, a suspended FB account, or a disabled Facebook account that we are already discussing here.
If you have:
Violated Facebook Terms and Conditions even after warnings
The pictures or posts that you have made on FB are inappropriate.
Created a fake account i.e. your profile represents someone else.
Spammed someone’s inbox with unwanted messages; this can get you in FB Jail as well as your account disabled.
Entered the wrong password several times, this can also get your Facebook account locked.
Joined a huge number of Facebook groups
