I first uploaded my series back in 2017 and things were different then: less vertical promote comics from Corea and Tapas used to highlight some indie content worth (the ones that are still high in each genre even though they are long abandoned).
There was less pressure to be chosen as a Premium creator too and page format comics were the majority. Now people draw vertical stuff to have more chances to be contacted by Tapas and be premium, ads pay waaay less than before and readers wants to read the corean crap they feed us (I'm tired to see Villaness title or the reincarnation trope).
