Have you look at the commits? A bunch of empty ones (seemingly all empty ones, though there must be some real ones in there somewhere). It's a bizarre looking repo. I don't even know how you make a repo look like that, but it certainly doesn't allow tracing of what code was added when and why.

It looks suspicious, even if it isn't. All those empty commits look like an intentional obfuscation of something, though I have no idea what.

It's indeed strange, it's likely some agent running amok. Doesn't look good indeed, but if I was interested in the project I'd still investigate the code itself
