The person I was refering is Karaol. Even the top image that is described as his own work and is used in the main Euroasia site without any attribution. You can see the image in the main site here https://euroasia-interconnector.com/at-glance/the-big-pictur...
The article fails to address the controversy between Greece and Euroasia interconnector. The only reference I can find is that in the top image, the line connecting Attika and Crete became dashed at some time. Also Greece cited that Ariadne interconnector is a company with only 25k capital and no previous completed project.
Maybe, but judging by the history page(https://en.wikipedia.org/w/index.php?title=EuroAsia_Intercon...), it was initially created by someone in the US and later edited by a diverse set of editors. So unlikely the entire page is an advertisement. If you see some specific snippets you think don't fit on Wikipedia, Be Bold and delete them (https://en.wikipedia.org/wiki/Wikipedia:Be_bold)
