I use tooling that I've written but also Imgbrd-Grabber to grab certain images for local caching and local offline storage of images for personal use only. Unfortunately, it seems that within the past week, all tools that attempt to download (including Imgbrd-Grabber and User-Agents such as "Danbooru user Darkness Eternal") are now being returned with API results data but 403 on every image, resulting in a confusing set of error codes on Imgbrd-Grabber (and more easily-understood errors on my Python requests tooling).
Is this a known issue, and are the sysadmins aware of the problem? This is *brand new*, and if you're doing a certain type of block that is trying to filter bots but not legit users, this is a bit of a large inconvenience (the CDN is where the forbidden errors happen, not the API).
