I refer to https://help.github.com/en/github/site-policy/github-subprocessors-and-cookies containing a long list of companies they are sharing data with, and a list of cookies, not all needed to create an account. But I don’t want to kick off a discussion about privacy. I had bad experiences and have taken consequences.
My question had the only purpose to find the most convenient way, accepted by the developers, to post an issue without using the Github web pages.
