The repository in question (https://github.com/BeRo1985/berotinypascal) is a small learning Pascal compiler, written in Pascal itself.

Github has blocked the repository without specifying a specific reason ("due to a terms of service violation").

A possible reason could be that there was an .exe in the repository that was compiled with a corresponding assembler. But is that really enough to be deactivated? Many repositories contain .exe files.

Is Github overshooting the mark here?

Not an excuse, but github has been under an attack whereby someone was creating thousands of repositories to distribute malware. I'm guessing this got swept up in the effort to prune out the real offenders

Yep, but given that the repo is many years old (possibly without any change), that's no good excuse, I think. :)
