I vaguely remember this happening with somebody on an Audacity project, so jumping in! I believe this was on a GitHub issue for that project, but the project has since disabled issues for the repository since they moved source locations. It also definitely hit some press.
If you are curious, some /pol/ and 4chan archives still have some stuff about the sneedacity incident available. There's still someone (a bot?) trying to recruit them to post shit about me from time to time.
