@Agent_Isai seems to work now.

Are there anyway to handle that automatically with mediawiki?
The wikitext I used was

[[File:Who killed Cock Robin? 5 Stars.png|200px]]

I checked around and noticed that pages that never got edited after imported (or after updated MW) seems to have this kind of issue.

The file https://houkai2nd.miraheze.org/wiki/File:Infinite_ammo_during_combat.png is used in https://houkai2nd.miraheze.org/wiki/Category:Infinite_ammo but it was listed as unused which is kind of weird.

Definitely not infobox bug, checked another file that got the same issue
https://houkai2nd.miraheze.org/wiki/File:Infinite_ammo_during_combat.png
https://houkai2nd.miraheze.org/wiki/Category:Infinite_ammo

Seems like the wiki is working normal now

Given the length of time such information was allowed to remain on the BiliBili platform, I'm not terribly confident in the responsiveness of the BiliBili's Data Protection Officer together with BiliBili's legal jurisdiction in which they operate.

Not sure when did you see those stuffs but recently, the Chinese's GDPR equivalent was launched and most of companies in CN are already comply the law.
And yes, the law doesn't have timescale required to process data but if the issue is big enough, the company's reputation will get ruined pretty fast (aka recorded in CN's Social Credit System and you may know how horrible it was).
It is also much faster to remove those by requesting to the gov in case of having serious issues (they do have pages to specifically handle these stuffs).

What's the specific need here, and, given my concern above, is there not a video sharing site the videos could be posted to and we could whitelist that? For example, YouTube, or, failing that, a site like Google Drive (if that is already whitelisted), the The Internet Archive, or similar.

There are stuffs that can't be posted outside of the requested page (both personal issues and since most videos on that site mostly have owner's signature embedded), attempting to post the video to other sites is basically breaking the ToS on both sides.
My best bet is to only whitelist player.bilibili.com (aka only video player) in case of security or privacy concerns.

• About GDPR, it mostly goes through the 2 third-parties and you can opt-out right on the appsflyer website. For the Firebase, it's probably for people who use Google account on the English platform to sign-in.
• About privacy reputation from the above article (for the Chinese platform, not English one), it's the article is kinda wrong anyway as you can register account without entering any private information. The only thing that require verify private information is when uploading and commenting which is required by the Chinese government. And technically you can't verify account to upload as a foreign user unless explicit consent by sending an email, the automated verify system only accept Chinese info.
