Hello guys it TKATECHY😘...

I discovered this little trick to know if your Facebook account  have been hacked.

type @[4:0] without spacing on the comment box of your account and click post. If it show Mark Zucherberg then your account is safe but if not that means it is hacked. Quickly change your password.
