This question comes from this list of edits: https://mathoverflow.net/posts/86827/revisions
An old answer included a link to a now-deprecated website (which has been taken over by a porn website); a proposed edit simply removed the deprecated website. I thought it would be better to keep the name of the website, but to note it was deprecated and remove the link, in order to preserve the intent of the original answer.
Searching for information on the old site, it seems to be a reindexing of arxiv (https://www.crossref.org/blog/eprintweb.org/), so it may not be necessary to list.
So which version is better? Alternatively, how should this be handled?
