A friend established my LinkedIn and Facebook accounts over a decade ago. I have never known the passwords for either account, nor have I ever accessed either account to update them or provide any information about myself. Recently I have been the subject of personal attacks on Facebook where one or more users (former friends, including one who does know the password to access the account) have posted false information about me, knowing I don't have access to that account to change the information. The false information they have posted is publicly available for anyone to view, and introduces jeopardy to my job as my employer occasionally investigates social media postings. While the offenses to date have been limited to Facebook postings, I want to delete my LinkedIn profile entirely before the postings spread to LinkedIn. I am desperate to do this immediately, and need help from LinkedIn to do so. I can provide you with whatever verification you may need to demonstrate that I am the person in the LinkedIn profile. My name is Christopher Lamar Saucier. Please contact me as soon as possible to help me resolve this issue.
