I mean, I've got tons of it, but most people aren't diy people, especially ones that live in apartments and come on here asking about filling holes.

I agree that holes larger than nail/pin size are appropriate to fill and said as much in my previous comment. I wouldn't make holes that size in an apartment wall though, and so wouldn't have much use for filler if I lived in one. And, if a landlord is asking for pin holes to be patched, toothpaste is as good as anything, considering that it's a completely unnecessary task in the first place.
