I notice the MyStorm entry in a fresh Chrome tab was adorned - is adorned - with a random icon from other sites. A possible reason is that this site does have an icon configured but the icon file itself has gone missing.
<link rel="icon" type="image/png" href="/uploads/default/original/1X/b05dc318e92e817b8303d32639390d64aa9ef214.ico">
I've a recollection that in discourse there's a hidden thread "Assets for the site design" which is used to ensure that files don't get reaped as orphaned when they don't appear in any thread. Not sure if that's part of this.
