You mean other than they're completely subjective pools with no real standards or guidelines? The observation that you're the only one adding and deleting posts suggests "favorites pool."
Did you check all the histories of the pools in question? In my experience, it would be only natural for any pool (regardless of their value and standards) created because only one person designed it, to be reasonably expected to be edited by only that person, for a relatively short period of time. However, all these pools were further edited by more people as well, except "Hot Waitress".
They're just as subjective as other themes like "Perfect Breasts", "Stoic Beauty" and "Badass Adorable", which rely on characteristics such as sexyness, beauty or cuteness. If the text explaining the guidelines and standards of "Hot Teacher", etc. can be improved, I'd suggest doing so, instead of outright deleting the pools in question.
One notable unspoken rule of these pools is the fact that all images share a certain degree of quality; "Hot Teacher" is not just a mere imitation of the tag teacher (or only a list of the tagged female teachers), but lists the most attractive ones, with "revealing" clothes, as required — at least in the opinion of the editors; most noticeably, my own opinion as the creator, of course, as if it were a "favorites" pool like you mentioned, despite it being subject to the views of any other editors.
I clearly noticed that some degree of consistent quality also governs the pool Perfect Breasts (pool #1677) without the need of explicit rules to that purpose. Its description is absolutely simple ("Area for perfect breasts." and nothing more), yet many people selectively add posts to it regularly, and remove some of them occasionally.
