Oh shit. I just looked at Comico, and that theory just seems on point. The two look the same, some of the comics are the same generic looking one's that are labeled Smackjeeves "Exclusives".
It's just sad that they used the Smackjeeves community to try and propel themselves, and in the process, just ended up alienating them and destroying the website. I'll be honest, before the update, I did kind of get the feeling while SJ was drying up a bit. Maybe fine on comics that were currently on it, but new comics were a bit few. But now...it's kind of a ghost town. Honestly, I'm trying to get the author of one comic, Cafe au Lait, to try and at least consider moving to Tapas or Webtoons cause I don't want it to just die there unnoticed.
As for the forum closure, I knew it was being locked permanently, but didn't know it was being removed. Or at the very least, when it would. This doesn't really surprise me because, well, you think these people give a shit about Smackjeeves, it's community, and it's past?
Sigh. This just sucks. I'm honestly worried about the website, and especially older comics that aren't on Tapas and Webtoon. I really do feel like this might go the way of that website you mentioned, Inkblazers.
