NuGet prefix reservation: LibGit2Sharp

There are a ridiculous number of packages in the nuget gallery that are named LibGit2Sharp. Some have version numbers greater than our own, a bunch include ssh binaries, and most have security vulnerabilities (but I repeat myself).

This is confusing as hell, and they're all using libgit2 trademarks and icons so certainly appear official. They're not.

I've contacted all the publishers and asked them to de-list their packages and mark them as deprecated. I'll follow up with a takedown request to nuget.org.

You can reserve a prefix in the NuGet gallery, so we could reserve the prefix. I think the LibGit2Sharp project should.
