An online game is using Dreadnought artwork for there game and or advertisements to attract players. More than once I have found this add on YouTube.
This is a screenshot of the YouTube page while the add of theirs is displayed. https://prnt.sc/YnjP5bdwRR3d This screenshot was taking by an app called Lightshot.
You can clearly see that the ship they are using is an Oberon Healer.
