The URL is on the left of the submission title.

Is this somehow related?

The submission title is actually "txet lanoitcerid-iB", with a Right To Left Override control character at the front. The whole line is in reverse it just doesn't look like it when rendered in your browser. There's a variety of control characters in unicode which let you stack, reverse, raise and lower individual pieces of text as you desire.

Interesting, I viewedmthe source of the page, and some of the tags are reversed too.

Is this an exploit/attack vector?

[cbd1984]

Anything that can confuse a person is a potential exploit vector.

That said, I don't know of any specific exploits which rely on this behavior.

Take a closer look at the URL while you're at it. It may look like an obscure domain, but its really not.

Yes, right click -> inspect element on the link.
