fake facebook account

Project description:

Iv recently found out that my ex has a fake facebook account and been monitoring me online, messaging anyone I take on a date, messaging people I chat with on line and accusing me of all manner of things in private messages 🙁 the account has been reported but as its over 3 years old now, has thousands of random friends and posts daily its seen as legit !! she has at last count 6 other accounts including her own but the account in question is used to gather all the information so security will be minimal,  I want to gain access to this account with a view to seeing who has been messaged and what has been said then permanently delete it  !! as a professional courtesy I will require proof of access to the account by way of a small undetectable alteration to be discussed in person
