Seems those share limit links are fine now, but if these arent your links, you should maybe skim and re-upload on your own so the longevity remains. As well as the content being validated 👍
So I think what I'm gonna do is just post random ones that I have. You may have them, many may have them already, but someone will appreciate it as they won't have them. So in future apologies if it isn't 'new' but just skip until I post new in...
