At approximately market close, I will visit the following page in an Incognito window: 

From that page, if I'm able to view Elon Musk's latest tweets without logging in and without any modal pop-ups preventing page interaction, the market resolves NO. Otherwise (if the page goes to a login wall, or if a modal login pop-up prevents me from normally interacting with the page, or if the tweets shown are out of date, etc.) it resolves YES.

If others are able to check at the exact close time and provide screenshots I will accept that as proof unless there's reason to believe it's fraudulent. Otherwise it will be based on whenever I check, even if that turns out to be a bit later than the exact close (could be up to 48 hours, though I'll try my best to be quicker than that).

Any changes to the login wall between now and close don't matter, just the end state at close time as described above.

Rules are similar to the previous version of this market, except that notably now this market will resolve YES even if there's no official login wall, if the logged-out version of the page shows tweets that are out of date.
