The description says "share a link to a question on social media that gets 5 clicks".
I've tweeted a question that got over 5 clicks. I've posted a share link in chat that also got over 5 clicks. Both of these had my user ID number in it and were clicked by different people.
I watched in real life as the twitter link was clicked, by family and friends, on different computers each time. It's not a problem of the same IP. (no wifi network overlap either)
Why haven't I gotten the hat? For the record, it's been almost an hour by now, so it's not hat lag causing the problem.
To clarify: the clicks were opening the share link in the browser, which redirected to the full url. The link was this.
