What ever happened to the Exhibitionist College Girl series by Maruta? I remember it being fully translated on panda then it got pulled and everything was removed.

Yeah, I've been noticing this with other artists as well, one or two of their works randomly disappear after being there for years, but their other stuff stays intact.
Maruta isn't a wani artist, right? Otherwise they would remove everything, not just a series or two

Most authors have works serialized in multiple magazine by multiple publishers, in fact.
The only author I can think of who has stayed consistently Wani over the years is Meme50, I think all of his magazine stuff so far has been published under Shitsurakuten
Anyway yes, MARUTA's main magazine is Penguin Club (non-Wani), but the Exhibitionist series was published under Shitsurakuten (Wani)
