OP downloaded a fake game that was quarantined in the meantime. That is why it's gone. It looks like a hacked account of a hobby dev that has some regular fan games on it and some fake games uploaded by the hacker.
This is not about any dev lacking respect. It is a plain malware scam. Itch is a honey pot and their scanners and hacking detection might just as well not exist at all. Or how many hacked accounts are acceptable? Because I see about ten per week without trying. Sometimes more.
Anyways, you do not need discord for the things described in the warnings about the try my game on discord scam. You need only upload it on Itch and wait.
