Yo. I've been on Tapastic since 2013 (according to the upload date on my manga page). I still called it Tapastic for few years after the change.
I remember the support program /cry.
My personal experience: Freshly updated comics would appear on the front page, or with the Fresh tab, it made it possible for people to explore whatever is available rather than what has the most views right now. I believe that is what allowed me to gain a following when I was active back then.
The website still tries its best to be as creator focused as possible. But you have to try to understand why certain genres started creeping to the front of the page and it has to do with their algorithm for Featured, Trending and Popular. They were pretty transparent about what they measured, though I'm not sure if I can find the explanation easily now. It didn't start with preferring romance and BL, but when those genres are what were hitting the top charts, other creators follow
Romance and BL are very popular and they're also very easy to make. The thing that would always make me laugh is how all you gotta do is make a thumbnail that says "BL" in the corner (and a cute drawing) and an instant 2k followers, when this trend first started.
Do note that it's harder. But it's not too difficult because some good stuff does make it on Trending. I'm not sure if Trending vs Popular changed so I won't say more but there's some unique, oddballs that make their way through. It's always gonna be harder, you gotta capitalize on the opportunity when Tapastic started then hang in there.
