Misattributing the official Guilty Gear account

The artist tag Hidehiko Sakamura is linked to the official Guilty Gear Twitter account. While Hidehiko Sakamura is indeed chiefly responsible for the arts of many Guilty Gear games, the Twitter account posts arts from Arc System Works' other in-house artists too (like this piece by Kitazano Shoichi.) Can we do something about the tag?

If it's not the artist's own account and there are works from various artists posted on it, it doesn't belong in their artist entry. I removed it.
