Agreed, no doubt about it.

What sort of content? All the content I've judged to be of public interest and uploaded to Internet Archive, is still online there today. But I'd understand that depending on the type of content, that might not be true for everythibng.
Someone dumping their Twitch stream or random Youtube content into the storage system will certainly have that content deleted and be banned if prior arrangements have not been made, for example. Don’t do that.
