This is mostly about 4gamer.net. Last year I mass tagged posts sourced from 4gamer with third-party source because they're a Japanese video game website related to game companies, not artists, and without a tag, it looks like the sources of the posts are a first-party game or artist website. 4gamer is the most famous but not the only Japanese website that receives and shares info and illustrations from companies to promote their games. However, news websites in general can often offer higher quality images and even images that haven't been shared by the actual games' websites or social media. 4gamer especially is a highly trustful source, but tagging it with third-party could carry a bad connotation.
I corrected all the bad links, prompting me to doubt my past edits and undo everything. Looking back, what I did was pure vandalism, I should've asked people before mass tagging third-party. There are a few dozen posts left tagged third and second party that I didn't touch, while almost a thousand posts have no tags. What should be the standard for 4gamer and similar sites?
