What legal obligations apply to delay of account deletion of 60 days

OOoooooooh. Yeah, that would make sense.

Wait though, if they demand the data be kept, why delete it at all?
What if they committed something right after the account expired?

Although, I think it would be more related to the website.

If the website had something illegal and they decided to delete it, that would make perfect sense. They could investigate it for some time before coming to a conclusion.
