My take on this, which I hope people don't find upsetting can be summed up as:
If you just soley want to make comics or novels as a hobby to hang out with people, and are genuinely upset by the idea somebody might assume you're trying to build an audience and might judge your work on how well it attracts and entertains readers, put your stuff on an appropriate platform for that.
Put them on The Duck or Comicfury or Deviantart; places where primarily comic creators both post and read comics, so everyone reading appreciates the work that goes into a comic and isn't expecting polished entertainment, the top performers usually only get a couple of thousand subs, nobody really makes money. There are also tons of places to share writing done just for fun to hang out with other writers.
Because on Tapas, over 90% of app users are readers, not creators, and they're here to be entertained, not to look behind the scenes and hang out with creators. From their perspective, they have no way of knowing that you just put your comic or novel up on the app just to hang out with people. How would they know? I'm pretty sure the people who upload their work intending to build a following would feel insulted if somebody said, "Oh... you're just making this for fun, right? You're doing great, honey." In my experience, it's way more insulting when you're genuinely trying to be professional and somebody is like "It's SO cute how you do those little doodles as a hobby!" than if you put your hobby work in a professional space and somebody is like "This is pretty good, but you should present it a bit more neatly if you want to get more people buying."
Putting your work on Tapas without wanting an audience to see it is like if instead of strumming guitar in your garage with some friends, you went to an open mic night at the local pub, and then when everyone was like "er...." at your random strumming and fragments of songs you mumble along to, you said to the audience, "Oh, I'm not performing for you, you're not meant to see this. I'm just practicing!". If I was at that pub, I'd be a bit confused.
People might call the readers entitled for expecting free entertainment for nothing in return, but isn't just expecting free hosting and listing in an index of works with a chance at visibility and features on not just a site, but an app with millions of users for nothing in return also a bit entitled? If you're uploading with no intention to build an audience that generates ad views and donations, your work costs more to host than it generates, and you're basically relying on those people whose work draws in an audience and so makes Tapas money for that free hosting to continue existing. Tapas lets you host your work for free, with the "payment" being the assumption that people who post will at least try to entertain the users and generate engagement.
