Unfortunately pages are still blocked when you try to access them with this script working using Tampermonkey. I did delete all my cookies beforehand and then entered using a VPN to ensure I had access beforehand.
Sorry to hear it didn't work for you! There might be some difference between our environments that makes it so the same script doesn't work for you. You were able to access blocked pages after deleting all cookies it looks like? I attached a more aggressive version of the script that automatically deletes all cookies from dlsite except for "adultchecked", "locale" and "localesuggested" as deleting those would lose your saved locale and cause dlsite to constantly prompt you for your age and location.
You can give that a try, there are a few things you can attempt if it is still not working:
Verify that you are able to access blocked pages after deleting all pages and using a Japan VPN. (I tested with UrbanVPN) Ideally note down the URLs for a few blocked pages.
Generate the cookie by connecting to dlsite without a VPN or with a VPN from a geoblocked country and verify that you are blocked from viewing one of the pages.
Enable your VPN and the tampermonkey script and open one of the other blocked URLs. (I'd suggest trying a different page since it seems like an individual page can be blocked for a while even after deleting the cookie.)
Press F12 while a dlsite page is open, and see if the "Deleting cookies" message is printing in the console at the bottom. (If not then make sure the script is active and running on

You can also try deleting the cookies individually without using the script. To do this, press F12 to open the developer console, then click on the Application tab at the top. Expand Cookies on the left bar and highlight the

URL. This should give you a list of all dlsite cookies which can be deleted. Try deleting the "_inflow_dlsite_params" cookie and opening one of the other blocked pages.
You can also try deleting other cookies one at a time to narrow down which is causing the problem. There seems to be some sort of geoblock that doesn't use cookies as well though, when I tested with a single page I found it didn't unblock even after deleting every cookie, but I was able to access other blocked pages.
