I like the intent of your ideas, we have thought of them before, here's some info on where some things do already exist and some reasons why we dont do others
Some terms will help:
1 is a prefix and can only be added by thread starter or a moderator.
2 is a tag and can be added by the thread starter or anyone with simp council so far more users than just the mod team.
The tag cloud
https://simpcity.su/pages/tagcloud/ picks up on tags across the entire forum.
There are already tags for nude etc. but it seems people dont use them much.
Threads like that are the exception not the norm, most girls dont have someone buying and posting every single thing they put out, for many that's prohibitively expensive and it puts a lot of work on that person to keep their collection up to date. Some threads it will happen, most it wont, its far more likely for threads to have many people buying and posting the content spreading the cost/effort over many.
People could always post an archive link in one of their first posts and just update it as others post in the thread, but there's no real reward for them for doing that, they dont get the likes and people already have the content so this is rare.
This is a possiblity, problem is people misusing it or people complaining about links being down that aren't.
Examples:
Bunkr geo-blocking countries like India / Indonesia because of repeated abuse, we tell people to use a VPN to Europe or similar, people still use VPNs to another part of India and then complain
Zippyshare (RIP) geo-blocking UK, Germany and others
Gofile who have temporary outages often and did have some storage servers that didn't work in all locations for a couple months
Saint vids, some iphone users cant see vids, none of the staff are able to replicate this and no-one has come forth with anything to help us fix the issue
We did add the done reaction recently for the camwhores / upstore threads so a reup reaction might be something we add
