Well keep in mind this Wikipedia Page actually belongs to a well thought of South Korean Actor. I thought it would be interesting for someone in his camp to figure out that there was an internet character out here making a lot of money with Seo's likeness. Every image is under copyright, so they could, in theory come after Haejin for every penny earned using that image.
I would not make a point of making too many additional edits to this particular Wiki article. But if you have something worth taking the risk with, have at it!
