Similar to T164553, EBSCOhost is a major, paywalled database. [[ https://tools.wmflabs.org/iabot/index.php?page=manageurldomain&domainsearch=search.ebscohost.com&exactmatch=on | Its archived pages ]] always link to a login screen. Some of the links (those with `db=a9h`, for instance, which were 15% of the results) do redirect in-browser to an abstract of the cited article, but their archived links do not.
Example:
http://search.ebscohost.com/login.aspx?direct=true&db=a9h&AN=5331234&site=ehost-live will resolve but
https://web.archive.org/web/20180429204700/http://search.ebscohost.com/login.aspx?direct=true&db=a9h&AN=5331234&site=ehost-live won't
So the `search.ebscohost.com` domain should be whitelisted ([[ https://tools.wmflabs.org/iabot/index.php?page=manageurlsingle | "treats the URL as alive and locks it in that state so it cannot be modified by the bot" ]])
Happy to assist with stuff like this, especially as the whole ebscohost.com domain needs some configuration, but I think whitelisting/blacklisting full domains requires a user right, if it didn't before
