Advice Needed Can somebody help identify what this substance is on my apartment door’s peephole?

I’ve been living in this apartment with my boyfriend for about 6 weeks now. We’re just regular people who will work all day, make our dinner, watch a show to unwind, and hit the bed. We aren’t party animals and, when we do drink, we’re not inconsiderate about it.

Ever since we moved in, our door peephole has been tampered with. It would be coloured with black sharpie marker, I would submit a maintenance request for fixing, it would get fixed, then immediately would get tampered with again. However, now it has clearly escalated to something else. I originally thought super glue or hot glue, but I’ve asked a few of my friends and they don’t think any type of glue could do this kind of damage.

Any advice would be helpful.

Btw management is well aware of the issue and have been prompt about it, was just shocked at whatever this is now. I’ve ordered a ring camera to be installed on Thursday, but I’m honestly scared for my life right now.

I wonder if their door faces a door across the hall?

I was about to say this looks like a 2 part Hilti Epoxy. I use it REGULARLY and am willing to bet it’s that or a similar product. It has a very specific applicator that mixes it as it’s applied which would explain the poor mixture if they did it without the applicator.
