I don't think there's rhyme or reason necessarily to some of the subscriber/like trends here or anywhere else, it just is what it is, for better or worse.
Webtoon is a bit more restrictive than Tapastic, which has shown itself to be a bit restrictive lately. So there's also that to think about. Just different platforms, even if the level of creator censorship isn't necessarily considered.
I'm not particularly motivated to try posting on Webtoon, especially since it seems to be far more censor-happy than Tapastic. I refuse to censor my work, because frankly it's restrained enough! Hearing that the audience at Webtoon is more demanding, as readers and not creators at all, is discouraging. But it's also worthwhile to mention that only a handful of people at Tapastic are actual creators. It's the creators, generally, who are active on the forums, but that's a tiny minority of all the site's userbase. Most of Tapastic's users are readers and not creators.
