Not sure if she's even still active as her last posts are from months ago, in any case there's nothing on the free tiers worth posting, the best stuff is already on the free sites and she's one of the worst scammers i've ever seen, on her website she lists videos like "Diana vs BBC" which don't exist and are meant i suppose to sucker people into signing up for ismygirl. Also looks like she's got a book out, not about sex, but rather about making money which should give you a glimpse at her mindset.
So yeah, she's just in it for the money and probably has more than she knows what to do with for now, expect maybe a few more videos when she runs out of cash again but remaining subbed to any of her stuff long term is a waste of money.
Also despite a lot of promotion about going maskless all her stuff is masked and probably always will be that's why i say she's a scammer going out of her way with false advertisement to get people to sign up to her subscriptions for nothing, she plays this game where it's always coming "soon" but the "soon" never arrives and she just keeps moving the goalposts, it's a deliberate game some girls play to keep the carrot just in front of the horses (us) and keep us paying them for nothing
