. [I post a photo thread.](https://kbin.social/m/wizardposting/t/413339/My-favorite-magic-ability) I go to my profile and see the thread. I cl](https://media.kbin.social/media/9e/0d/9e0db5f655d57cae4b07072fb9284e624edffb9e9c8e79615f3082018c916abe.png){kind=link}
So funny thing about #kbin. I post a photo thread. I go to my profile and see the thread. I click on the image preview icon. I immediately get sent to https://kbin.social/u/undefined. Not only is Mr. Undefined a real user, hello @undefined, but somehow my image now directs to his profile.
As I dig into Firefox dev tools to find out why, I see that uBlock Origin has blocked the request for my image. But that’s odd, I have no specific blocking rules for kbin, and kbin.social doesn’t run ads. What’s up?
So it turns out my image got uploaded to the following URL: https://media.kbin.social/media/ad/b2/adb203028331eada7f99f2b4547cbc0a7efc0ba4e203a71d9d193c02d38aa4f1.jpg
…/media/ad/… That’s what uBlock was upset about. So by blocking that request, the target of the AJAX fetch is… undefined. Hence my trip to a random user’s profile. XD
So if you’re a kbin user and for some ungodly reason you find yourself on Mr. Undefined’s page after previewing an image, you may want to add the following rules to your ublock origin list.
