I feel like the conspiracy theories are going way out of control here. I still believe something fishy is going on, but trying to confidently speculate as to what that something is or act like we know what it is, when we have no reliable information to base it upon, is unprofessional and might actually hurt us more than help us.
Let's stop any confident claims that Webtoons is cheating the system to promote this or that comic, because it is simply unfair. Many of the specifically targeted comics that have been mentioned in this thread already came from creators or groups that had an established audience and style. Them gaining traction fast is simply natural, since people have already heard about them and some fans jump on it to boost it early. Claiming this is webtoons cheating these people into success is harmful and ignores the hard work these people put in for many years to build their audience. It also does us no good in regards to learning a better way to success.
Let's wait and observe before making assumptions and spreading rumors. Good thing to keep in mind for us all individually is that if you present yourself as irrational, jumping quick to assumptions, or other unprofessional behavior, then there's a risk that companies that could be potentially interested in hiring you or getting a contract with you will get a bad taste in their mouths and may not want that anymore.
This being said... if webtoons are cheating the system in any way, then I think it would be by forcing unsubs. Some people have found themselves unwillingly unsubbed from comics, so this is a theory that actually has a basis. I see no reliable evidence implying that webtoons is cheating people into gaining subs, however, besides natural promotion techniques. If anything, there is a group of the webtoons readers that are ganging up to upvote or downvote comics, but that is not something webtoon can control.
Here's an important thing though: The unusual amount of lost subs could be manipulation. Or it could simply be a bug. Because this is a thing that I've recently learnt has happened on other sites too. Bugs are a thing
Regardless of whether it's a bug or manipulation, the unwilling unsubs need to stop.
