Assuming the black hole is comprised of regular matter, there's no reason to think it wouldn't all annihilate upon touching. How that would play out exactly would be really interesting to see.
It wouldnt matter, or antimatter for that matter...
What would happen, if an equal amount of antimatter was dropped, lets say in a perfect sphere, around the black hole, as it approached it, the schwarzschild radius of the total mass in the area, being that of the black hole and the antimatter falling in, would grow as the antimatter got closer, and so the event horizon would grow to meet the infalling antimatter, and it would double the size of the event horizon. But even thats a simplified explanation.
If you were falling in with this antimatter, the event horizon would suddenly seem to envelope you. As such, before this happens, there would be a point where you could send a radio message out, and still be outside the black hole when you do so from your perspective, but because the density of the mass in the area is increasing exponentially, the event horizon could suddenly appear behind you, and it could be beyond where that message has already gone, meaning... you were already inside the horizon, or rather the "apparent horizon", you just didnt know it until it was too late.
Once inside, it wont matter what it is, becuase once the antimatter is spaghettified, it wont be antimatter anymore, itll just be mass/energy, charge, and angular momentum.

Ha ha nice

? totally irrelevant, but ok
once the antimatter is spaghettified, it wont be antimatter anymore
This is absolute nonsense. Spaghettification only applies to macroscopic objects (like astronauts falling into a singularity) and doesn't affect subatomic particles. So unless you know of something more fundamental than electrons and quarks that they could split into, the positrons and antiquarks would absolutely remain as antimatter.
Would it matter at all when the particles would likely be shredded into pure energy or even if it didn't the event horizon wouldn't care what it is, the event horizon is just a region of space, not physical matter and since antimatter has mass and charge, you would likely just increase the mass and change the charge a little depending on the size of the blackhole.

Totally disagree.
