E.g. you used a service like for job hunting, submitted personal data, landed a job and are now done with it.
I first change my information then delete it. So IE say my name is Don Brown. I change it to Jack Thorton, wait a few days and then delete.
I change the email address before deleting. If the deletion requires email confirmation, I'll change it to a disposable email address. Otherwise, I'll make up an email address with a nonexistent domain name
Yes, unless that service is the kind of thing you think you might pick up later.
For instance, you might use LinkedIn to find a job, but that can still be something you might need in the future, because it's unlikely you'll hold that one job forever, and intermittently posting during your existing job could actually help your future prospects.
By contrast, if you used a random site to create a fancier resume, yeah, that account can go straight in the digital wastebasket when you're done with it. You can always make a new account if you need to make a new resume, and it probably won't rely on your old account's data to get that job done.
