The flowgrind ebuild has: HOMEPAGE="http://flowgrind.net/ https://github.com/flowgrind/flowgrind/" flowgrind.net appears obsolete and is pointing to a domain parking service. The current webpage appears to be: https://flowgrind.github.io/ I think it's not needed to reference the github repo in the HOMEPAGE var, as we have remote-id in metadata for that (it's already in there). So I guess this should just be: HOMEPAGE="https://flowgrind.github.io/"
