Very likely any DM chatting and wall posts are written by an agency. She has too many fans to realistically be able to talk to everyone herself. She also doesn't seem like the type of person to stay home online for long hours when she could be making new content or having fun doing non-porn stuff. If her greenlight status is always on (online & available) that's also a dead giveaway. She needs to sleep like any other person.
Also frequently promotes other girls which is a big red flag that the agency also manages those pages too. Yes some girls are friends and want to support each other and spread the wealth, but in the end they're all competing with each other for the same fans willing to actually pay for porn (most fans don't) so why promote another girl who might take away earnings from her? The agencies DGAF because they get a cut of every girl's page they manage.
Another thing to make it easier for her agency is this website that lists her content so fans can then DM exactly what they want and the agency can then make the sale ASAP

If you just want to buy content and don't care you're not talking to the real girl it would actually be better if more creators did this; having their content menu available. A real clip store (ManyVids, Clips4Sale, APClips, PornBox, LoyalFans) would be better but too many girls are stubborn and refuse to leave OnlyFans because it's the most popular and has better payouts. They'd only invest time & effort on other platforms if somebody else is willing to do the work for them (for an appealing price) or their earnings on OnlyFans start to dry up and have no choice.
