That may tell more about the beholder than you think.

> Only LinkedIn showed the link between the HN profile and the Github profile, because it lists both the project mentioned on the HN profile as well as the project listed in the Github profile.

What if there was no link between the HN profile and GitHub, then? Would you conclude that, because you can't reliably link the HN profile to the GitHub profile (that was independently already trustworthy), this would make the project seem suspicious?

In other words -- Would your projects be more suspicious, if I, a total stranger, made Show HNs about them?

You're seeing my point, don't you?
