Tapas' perogative as a content delivery service for custom-tailored media would be to direct the viewer's attention as much as possible to their own stories, and to shove every single other one in a bin until it's ready to be featured. This is how they make absolutely certain that, for better or worse, readers (especially young ones) don't have bad or boring experiences with unmoderated, unpolished content that can cause them to associate the platform (and therefore the app, which is their primary source of revenue through ink) with garbage.
If you're better than garbage, you can't ask them to prove it on your behalf. You have to make use of social media and your own connections in order to give the general userbase a CHANCE to DECIDE if your work is good. Then you can self-promote and improve accordingly.
This means you actually have the burden of effort here, not them. They make nothing from you even if you're the most popular independent artist on their website, because each page only generates one ad-view from each reader, and zero ink is spent to read your work. They'd prefer (like anyone would) that their tokens be used on content that they themselves have commissioned, as it guarantees that more can be made.
If you want to be heard, you can't always just speak louder - sometimes you have to speak in the right place, at the right time. Tapas, for you and I, is a HOSTING service, not a mentorship program or free sponsorship. For artists and creators who attend their actual, deliberately organized tutoring programs, it's a different story. We are COSTING the platform money even if we're the best ones on it, unless we're better than the best - someone who generates tens or hundreds of thousands of adviews in a single week and posts more than three times a week with content that the viewers actually engage with. Every time someone replies to a comment you made and you check back to see what it was and respond - that's a double-whammy for adviews.
Tapas, like any webcomic platform, is doing you a favor by providing the opportunity to foster your own personal bubble of a community of readers. At this point already, they don't owe you or I anything at all. That is how the market works because that's how the world measures quality - by impact.
If your webcomic is underperforming, spread out onto other platforms and try social media sites. You might need to diversify your output if you discover that you actually cannot make a meaningful living or garner a significant audience from your work, because even if it's good, it might not be SEEN as good at the TIME when it's viewed.
Whether you're an artist or an entertainer, you have to funnel several resources into your work or it will fail. Media cannot live by media alone, but it can definitely die.
