Changing the title of an issue, presumably so it doesn't show up in search results? Deleting the body of the issue? Not leaving any explanation? Yeah, that doesn't seem normal to me. Can't say I approve.

Looks to me like someone posted spam and it got removed. And yes, unfortunately, that's a thing on github these days.

Unless the title was lifted from another issue for the purpose of spam...

...this actually looks like a potential security weakness that was purged from the public space. (CWE-921)

it wasn't purged, per say. if you click "edited by maxtaco" on KirtiRamchandani's first comment, you get a dropdown to select the versions, and you can still find the original text.
