When someone preys on a person, using some or all of the following tactics:
* controlling who they can talk to
* intercepting messages / attempts by the victim's friends to communicate with them
* insisting the victim spend all of their time with the abuser, not the people they want to be with
* forcing the victim to spend more time with and attention on the abuser than they want to
* controlling the victim's other sources of information
* destroying the victim's ability to trust others
* manipulating the victim to establish control by shame, insult, or other emotional abuse
... sometimes we call it "domestic abuse".
Other times, we call it "Facebook".
#Facebook is designed to make you miserable. It's much easier to get miserable people to give up on life and spend all their time doomscrolling through ads, "sponsored content", and other crap to drive "engagement" and goose that ever-important "minutes spent per day" number.
Refuse to participate. Delete your Facebook account.
#Zuck's latest announcement of going full X / fascist, rather than just part, is just another reason.
