It's an anchor tag.

Here's an example: yahoo.com

You think that links to yahoo.com? Nope. It links to google.com. Even though it's a very very very old trick, it's honestly very deceiving especially to the uninformed; though with time knowing this sort of "trick", you'd get cautious everytime you see a link on forums. Always hover your cursor over the link and check where the link actually leads to.
