So I've been browsing through John Persons pics, and some of then have come back as blacklisted.
Now, I put my blacklist as scat and guro, and I know that John Persons artwork does not feature any of that stuff in his art.
I cleared my blacklist, just so see what would happen, and it's still coming back as blacklisted.
Anyone got any clues?

What do you have your Post threshold set as?

How to blacklist some tags?

@Gloom, I've got it as 0. Which I don't remember setting it as. I don't even remember touching it.

The "My Account" tab :)

There's your problem. Any post with a score below your post threshold gets blacklisted. It is 0 by default. Setting it as a lower number will allow lower-scoring images to appear. I have mine set at -999 so I can see any image no matter how many people downvote it.

The lowest score I've ever seen was -85.
