If I can yeet my two cents into the ring here...
How does jaminis box plan to draw new readers in if they remove all of their chapters? Like, I get it, its a free product, the legal waters of scanlations are murky, etc etc, but... right now, at this exact moment, if someone wanted to read solo leveling, the only way they'd be able to find their website is by coming here to the comments. Searching for Solo Leveling translations doesn't bring up their website on major search engines, I just tried on google, duck duck go, AND bing just to be sure.
To those mentioning the discord: You're missing a key step. FINDING them. When they scrub their contributions to a site like mangadex, they're making it impossible to trace them back to their website to find them, which necessarily means that finding their discord is also impossible for anyone new. Yes, anyone who's been reading scanlations probably knows of them or how to find them, but again I'm talking about people who are literally just showing up TODAY. It's not drawing new people to their website, its having people walking into a burned out warzone where people are STILL fighting. Kind of a bad look no matter how you cut it.
