The only reason I'm making this thread is because at times it feels like things like handling artist rebrands and stuff can get messy and a moderator can come along and change it to something incorrect with little justification behind it, as was the case with aliasing claralaine to aoizuri, where for some reason one of the mods thought it was a good idea to change the artist's name to one of her alternate names that she uses in like one place and nowhere else. Because of not being able to include justification and proof that a change was erroneous without potentially getting a record for vandalism because it challenges what a mod did previously, now it's unknown on whether it's possible to make such a change.
As for a less personal reason, a ton of other places on the site have the ability to attach an optional comment to justify changes, I don't see why artist pages don't follow suit. Or is wanting consistency not something the site wants?
