I did not use the gog.com well anneyo not want to leave and leave an ID. I hope to leave or delete the ID.

Too late! You're stuck here forever with us! MUAHAHAHAHAHAHA!

...unless you contact support. I mean, you could do that, too.

You could quickly and easily unsubscribe to any email notifications, and then just go away and never notice all the game deals... as they won't pester you then.

I wonder what went wrong.

I wonder what ID he's talking about.

Click here to manage your subscriptions. You can unsubscribe yourself from all store notifications and you won't be getting any more emails from GOG.

It sounds as though you're asking how to delete your GOG account. To be honest, there's no real need to do that - just unsubscribe using the above link and stop using the website, and it will be exactly as though you never had an account here (except that if you want to resume using the site later then your account will be there waiting for you, of course).

But if you want GOG to forget that you ever had an account here then contact support using this form and set "problem type" to "account cancellation"

"anneyo"?
"not want to leave and leave an ID. I hope to leave or delete the ID"

WTF?

Your typing would be sketchy too if you shared a border with one of the craziest mother fuckers on the planet. :P

Maybe he's even using Red Star OS XD

If you just want to unsubscribe for gog newsletters see post above mine. If you really want to delete your account read this.

From FAQ:

11. How do I cancel my GOG.com account?
We have no idea why you'd want to do that, but if you will ever want to cancel your GOG.com user account, please contact us via the "General / Website questions" (https://www.gog.com/support/contact/general_website_questions) contact form. After verifying you are the owner of the account in question and confirming that you want your account to be permanently deleted, our support rep will mark your account for deletion. From this moment on, the account will be inaccessible, and after 30 days it will be irreversibly wiped from our database.Please remember that without an account, you won't be able to re-download your purchased games as well as any additional content available, including updates and patches. Also, we don't store your payment information and, if you don't want to receive newsletters from us, you can always unsubscribe via your My Account -> Account & Settings page.Most importantly, following the 30-day "grace period," account deletion is permanent. It won't be possible to “recreate” the deleted account later, if you change your mind.

To be truthfully honest, this seems unlikely. Very likely they keep backups, multiple backups, and unless the backups only go 30 days, then more likely a far reaching backup would hold the database entries with a person's purchases.

However it would be a pain to do, and is easier just to mark the account 'deleted' rather than to actually delete it.

I'm nowhere near South Korea and neither are you...

Huh? :P
