So am I right in my understanding that the main wrongdoing here is the plagiarized whitepaper? That's certainly wrong to do and doesn't reflect well on the integrity of whoever's behind the project, but that doesn't say much about how legit MetaMallVerse is or to what extent Royse777's reputation ought to be sullied.
Beside some other red flags like having anonymous team while conducting ICO and generally looking like very little effort and thought has been put into this project, you are right, the reason why MetaMallVerse account got tagged and flagged is due plagiarized whitepaper. Combine those two things and its pretty obvious how this is going to end up.
Not only the whitepaper, but also the website (and most of the content in the ANN topic) is also plagiarized from various sources, but mostly from the Cypherdog project:
https://bitcointalk.org/index.php?topic=5430836.msg61635556#msg61635556It's clear from a simple five-minute Google search that this project is nothing more than a simple copycat scheme. They take bits and pieces from other projects without any original ideas or concepts, just to deceive uninformed investors and make a quick buck before disappearing in a month or two.
