(TL;DR - she only stopped passes because her sister who ran it all for her decided to move on, now she might get a team to run it for her and go back to posting content like before)
Managed to catch her live a couple days ago, she basically gave a rundown of the passes situation and the reasons behind everything. She gave way more context but this is the gist:
Even though the leaks had got worse lately, she's always had leakers and it wasn't the reason she decided to stop. Basically her sister has been running her passes since the beginning (onlypaige too), doing all of it except answering dm's, but in June decided she wanted to move on and do other stuff. Paige initially thought she could pick up the slack and do it all herself, just with much less content (hence the "no more sexy content, my passes is going to look different" video back in May). Turns out she couldn't even do that with all the other stuff she's got going on, plus wanting to spend more time with family. She basically didn't know what to do with it because she can't run it herself and she's never wanted a team to run it for her. So she said she was leaving to stop people signing up in case she decided to quit. But apparently she's been coming around to the idea of having a team run it as long as it's transparent, and that way she can go back to posting regular content, plus racy stuff, like she used to. So either she'll do that, or she leaves it as it is now and barely posts. She wanted to get everyone's opinion, obviously most people voted for the first option, so she'll decide by end of July.
