Bug overview description.
im trying to blacklist mario_+_rabbids:_kingdom_battle but it does not seem to work.. all other blacklisted tags are still hidden normally. i think that it might be the + in there?

What is the expected behavior?
the posts with that tag are supposed to be hidden

What actual behavior is given instead?
they remain unhidden

Can you reproduce the bug every time?
yes

What steps did you take to replicate this bug?
made sure that i did not make any typos

mario_+_rabbids:_kingdom_battle is an interesting tag, with both a + and a :. I've tried replacing those seperately with wildcards, as well as both of them, but no go.
I've tested this with other tags using only one of the two, such as dust:an_elysian_tail and kombu+, and strangely, neither of the two worked in the blacklist, even when using wildcards such as *elysian_tail or kombu*.

While it doesn't fix the bug, you can circumvent it by blacklisting mario_bros rabbid instead.
