KissManga has introduced a new script to detect adblockers, before you get in. Showing a blank page with a "Please wait..." message with a countdown, until you disable your adblocker. This script (or it might be this one: https://greasyfork.org/en/scripts/4900-kissanime-anti-adblock-blocker) now also obstructs website entry, requiring disabling of Violentmonkey as well before a refresh, then you are allowed in. You can re-enable both add-ons once you get in and reload again, obviously not ideal to do this every time you open the site.

I'm currently able to enter the site without issue, with only this script installed.
