It's illegal nationwide as far as I know. The FTC's been cracking down on it.
I had a newspaper subscription that I wanted to cancel after they were bought by some crap private investors who wrecked it. I couldn't do it online and their chat agent just sent me to a phone number that rang forever and no one ever answered. I sent them an e-mail and made a quick report to ReportFraud.ftc.gov and the next day I had an e-mail from the newspaper confirming my cancellation and saying that their "cancel page was just temporarily offline." Sure it was.
@BE thank you for this information! This is wonderful news.
