LinkedIn had 164 million email addresses and passwords exposed. Originally hacked in 2012, the data remained out of sight until being offered for sale on a dark market site 4 years later. The passwords in the breach were stored as SHA1 hashes without salt, the vast majority of which were quickly cracked in the days following the release of the data.

2012:6.5 million users in June (stolen passwords)

Passwords for nearly 6.5 million user accounts were stolen. Yevgeniy Nikulin was convicted of the crime and sentenced to 88 months in prison.Prosecutors alleged that Nikulin stole a LinkedIn employee’s username and password, using them to gain access to the corporation’s network.

Our opinion

What is clear from this list is that your data is not safe on Facebook. More than 1 billion user records were leaked.

You should either delete your Facebook account or at least delete any information that could harm you. Don’t share anything that you don’t want to be publicly available.
