WotLK Saw an in-game message, unsure if legit or troll.

There was an in game message about a dedicated Warmane Launcher, and something about 30 free coins for installing it. Just wondering if this is a legitimate thing or if I fell for someone's trolling. Sorry if this was answered somewhere on the forums, I couldn't find it myself. Thank you for your time.

it's a scam
