That’s just quitter talk.

I highly doubt the electricity would flow to the pole itself at all if you connect both contacts to the top

That wiki says it’s common in hospitals and labs. Interstitial space is not the same as a floor cavity.

Also

The heights of these spaces are generally 6 to 8 feet (1.8 to 2.4 m) and allow easy access for repair or alteration

So yeah not common in a residential building.

My browser history now includes several Amazon listings for stripper poles.

I have learned that:

1. The listing ALWAYS calls them "dancing poles" but Amazon knows what you mean,

2. About half of them are sold as "unisex" even though all of the photos of them in use show women,

3. Only some require drilling into the ceiling. The few that do ship with screws or lag bolts that are approx. 2 inches in length and come with drywall anchors.

So, if installing any of the poles from Amazon's first page of results, your floor would have to be approximately 1.5 inches thick.

If the downstairs apartment had no ceiling treatment and you looked up at joists and subfloor, you might get here if she decided to attach between the ceiling joists. In a typical residential structure with a drywall ceiling, you'd need lag bolts some 10 or 12 inches long to reach through the plate of the pole, 3/4" of drywall, 8 or 10 inches of floor system depending, 3/4" of subfloor and 1/2" of flooring.

Thinner than the lag bolts are long...?

I got drill bits that can go pretty deep. The reason this shit doesn't happen to professionals like myself is that I am scared of electricity and power tools and have no clue what I'm doing and have people do it for me.

You can short the terminals on a car battery with your body with no issue (there's a theory that that's why you see it in movies so much - if anyone actually tries it the studio isn't giving them an idea that actually works. Same with duct-tape gags and chloroform), but it might melt the hardware and set the floor on fire which would be fun! What they should really do is connect a HV source and charge up the pole. Won't cause any lasting harm, but hopefully it'll convince them they drove a screw through a live wire.

I mean, a car battery isn't going to do anything even if you could complete a circuit. You can just grab the terminals on a car battery, 12V isn't high enough to be noticeable on dry skin.

You'd want to solder on the hot lead of an extension cord hooked up to 120 if you wanted to make sure they never touch that pole again.

Disclaimer: don't do this, it'll probably kill.

Seriously though, this is def something you take up with the landlord, the fines and payment for the repairs alone will be punishment enough.

That only solves your problem. It doesn't add problems for the perpetrator, which is the only thing we are concerned with here.
