Well, im just gonna write my thoughts and then disappear into the wind.
I believe she will eventually do proper nudes (nipples and holes showing) and eventually do solo porn stuff down the line. Whats holding her back is mental barriers she has set herself because she is still too religious or self righteous or some shit.
She is friends with novaruu, she knows exactly how these things go but because she believes she is god's present on earth she thinks she is better than that but we all have seen how this has been working so far...
Plus her father's death played its part in all this, when losing a parent, especially one that wasnt abusive (i assume, i dont know what was happening behind close doors) it takes a huge toll on you mentally and want to subconsciously please them with your lifestyle from then on ("they wouldn't approve that" or "they wouldn't want that for me" etc etc) until enough time passes to just not care anymore and do whatever you wanna do. To some it takes a few weeks to move on to some it takes years. Mary seems like the person that would need a couple of years, adding all the mental shit she already has and we can be looking at three years waiting time for her to embrace the e-girl career and start the nudes again.
Going forward in her life from here, i cant see what possible moves she has other than just finding a normal decent job or simply opening an onlyfans (unless she already is an escort for a select few). Her actions and behavior have only left her with her most hardcore fans (which are enough for now) but they wont last forever, they never do. I occasionally come here to read the news but its only just logging of her expected behavior to be honest.
Give her some time, she will eventually do something, that's a given, im willing to bet she made a fuckton of money from her previous nudes and since she saw how easy it was i doubt she would wanna go to a 9-5 job for x10 less than just taking snaps on her bed with her underwear. Plus she likes the attention around her (as we have seen with almost everything happening the last 2-2.5 years). So, be patient, it will happen, no reason to lose your cool and say "she is crazy" every other post.
