Certainly. But you have yet to produce any laws. Just a lot of hearsay and anecdote. If you believe Facebook is in breach of a contract it has with you please post the contract and explain the breech.
I just said you would say that! LOL!
Again my argument is there are no laws at all against what they're doing. Not even contract law. Everyone else needs to follow laws set down for contracts except social medias.
When you sign up you're required to agree to their terms of service. That is a contract which SHOULD be based on US or international contract laws. They don't.
The way they get around it is claiming there service isn't a platform and not a publisher. Which I posted a link from a law site showing that argument from social media's perspective.
Since they're not a publisher or a platform there are no laws created at all and are at the moment not bound by anything other then what they feel is best for them.
When you agree to their terms of service. They don't need to inform you of any mistake you might have made before closing your account. ALL other contract laws require a notice of compliance before service is closed.
