So it has nothing to do with any private information as the event was manually created.

I happened to mention in chat (Root Access) some time ago that my birthday was on Jan 22. Someone (I can't remember who) decided to create a chat event as a reminder so that the chat regulars could wish me a happy birthday ;) This morning the event appeared on the Super User upcoming events. So, as a room owner, I deleted the event. However it still appears as you have noted in your question :/

LOL. I've noticed that as well. I'm sure I seen the question before It is a bit of a giveaway ;) Ah, here it is Review - audit questions take longer to load?

What happens when you say yes to 'SU is asking for permission'? There is nothing stopping you being logged on using multiple different google accounts at the same time in the same browser. I quite often have two different gmail accounts open at the same time (in different tabs).

@MartyMacGyver Note that is this case, although it was an old question, the author was "Last seen Dec 5 '15 at 19:18" (from his profile page).

You seemed to have missed "Furthermore, it is not allowed to migrate questions to Beta sites (which AVP.SE is) from @slhks answer...

They should also use appropriate quote markup (>). See How to reference material written by others

@StijndeWitt We close questions when they don't meet the quality standards of SU. That's decided by the community. Questions acceptable some years ago are not always acceptable now (the site has matured and standards have changed).

1 more vote required ;)

If the replacement is also broken then reject the edit. I would select "causes harm - replacement link also broken"

It's fine to fix broken links. Just make sure you complete the edit summary to say "Fixed broken link" ;)

Of course you can create a blog. Somewhere else not on the se network ;)

If you politely ask on chat.stackexchange.com/rooms/118/root-access (with a link to this question) you may get another vote ;)

Currently it need one more undelete vote.
