I apologize if a feature request would be more in order. This issue has been around for a while, and I'd be happy to see it fixed.

Bug overview description.
When searching, there's a brief window of time in which all potential search results are displayed. A moment later, the user-side blacklist runs, and yanks any offending candidates out. This can give a momentary glimpse of unwanted or offensive content to those not expecting it, such as gore, blood, death, and slightly_chubby. ^;;)

What part(s) of the site page(s) are affected?
The Javascript that handles blacklisting results

What is the expected behavior?
The search engine completely prevents blacklisted images from appearing to the user, for any period of time.

What actual behavior is given instead?
For a moment (approximately 300ms in my case) all posts are displayed without any filtering applied, including the gory and explicit.

Can you reproduce the bug every time?
Yeperooni.

What steps did you take to replicate this bug?
Perform a search for any tag you have blacklisted. Sort by score_asc if you're feeling brave. Images with the blacklisted tag will briefly flash on the screen before disappearing, just enough time for a cheese grater or two to be permanently seared into the mind's eye.
