While I’m sure there’s probably some arcane legal course of action- why don’t you just block it or mark it as spam so it disappears? Easy in gmail.
On the other hand, if I could get statutory damages out of every poorly-behaved unsubscribe button, I’d probably be rich. My spam folder is full of them.
This isn’t what I do, but it may work for you. Log into your LG account and change the email to something fake or get a 10 minute email address and use that.
Be aware of the downsides of this approach. Two that I can immediately envision are recalls and notification of class actions. I’m sure there are others.
IMHO you’re 1000% better off spending your energy elsewhere.
CAN-SPAM act makes it illegal to not honor unsubscribe requests. You can report them to the FTC. but you’ve got no personal recourse to seek damages individually under that law.
What state are you in? Apparently some states have laws that might allow you to take othe legal action.
You’re 100% sure the email you are geting is sent to you and not forwarded?
