blacklisting stuff doesnt actually work it still shows up when searching tags
searched succubus got pics with blacklisted tags for diaper peeing etc
please fix

Is your blacklist set up right? Whole tags, one per line. Multiple on the same line blacklist the combination of the tags.

what do you have in your blacklist? because blacklist is working just fine for me and usually the problem is incorrectly set blacklist. each blacklist entry needs to be on their own line. for example having
dog cat
in your blacklist will hide only images that are tagged as dog AND cat

having
dog
cat
in your blacklist will hide images that are tagged as dog OR cat

also did you make sure that the post was tagged properly in the first place? the blacklist wont work if the post is missing tags.

Check if the post was properly tagged, otherwise the easiest way for us to help is probably if you paste your blacklist here.

Do you by any chance have JavaScript disabled? If I browse with it disabled my blacklist will not work.

Also make sure you pushed the save button on the settings page, I've forgotten to press that button a few times.

BE sure to have a look at e621:blacklist

if it still is confusing, post your blacklist here, and tell us what yo uwant from it. :)
