According to help:post relationships, the choice of parent post between identical images is governed by a priority system. Between any two identical images, the highest resolution is always the parent. Between two images of identical resolution, the least censored one is the parent. Between two equally censored images of identical resolution, the least compressed one is the parent.
This has been in place in the wiki since 2021 and was added by nonamethanks. It has been consistent site policy ever since (asset #44311966, asset #44311957, forum #419212, etc).
Recently, it has come to light that some people in discord have been giving the advice that resolution only takes priority over censorship when the difference in resolution is very big. When the difference in resolution is small, so it is said, you may make a uncensored smaller res version the parent. (Some people have even said that censorship takes priority always over resolution, but that appears to just be a simple misreading of the wiki.)
I don't think that advice is ill-intentioned and I'm not trying to lay blame, but the advice is, strictly speaking, wrong. That's not what the wiki says. That's not agreed to in any forum thread. That's contrary to statements from both admins. That's a new rule that has been invented by discord and is nowhere to be found on the actual site.
Anyway, there's two issues here.
First: should there be room for subjective assessments of which post is better?
In my view, the main purpose of our parenting rules is to prevent endless arguing from moronic builders who desperately want their name on the parent. We very frequently see people fighting to get their name on the parent, for some dumb reason, and it's very useful to have a very rigid, as-objective-as-possible system for determining which should be the parent. If the rules leave it up to discretion, then the inevitable result will be people tag-warring for pages of versions over parenting because one builder thinks their 1000x1000 uncensored version should be parent and another builder thinks their 1200x1200 censored version should be parent, and you can't really say either of them is wrong. It would end up being left up to either mod intervention or the whims of whichever group happens to be active on discord at the time.
"But what if this leads to absurd results, like an uncensored png being child to a extremely compressed, uncensored jpg?" Who cares. No, really. Which post is parent doesn't really matter at all. I'd rather have a rigid set of rules that sometimes places the "better" image as child then leave room for inevitable endless ego-driven builder tag warring. People will still be able to find the version that's "better" to them. On this topic, I'll point again to asset #44311966 which I agree with.
Second: which should have priority, uncensored or higher res?
The other major purpose of the parenting rules is to help direct users to the "best" version of the post. When this topic was brought up in discord, almost everyone agreed that uncensored versions are the "better" versions that most people want to see, and the strong majority was in favour of changing the rules so that uncensored is higher in priority to resolution. This on the grounds that a) the uncensored version is closer to being the "true" image that the artist intended, since file compression destroys less of the original artist's intent than censorship, and b) most gooners care more about seeing genitals than having more pixels.
I don't have strong views on this, but if I had to pick, I agree that uncensored images are probably the preferred images for most users. Personally, I would prefer to favourite a smaller res uncensored version over a larger censored version. So I'd be in favour of changing the priority to make uncensored images preferred.
