This was patched after a viral post was made about the same vulnerability. This page remains online just as an archive, and so the few links made with it don't break.
Wanna post a link, but have Twitter not notice? For some reason? This may be the tool for you ;)
For example, put a link to your Mastodon profile in the first input box, and put a link to Elon's Twitter profile in the second box to make a link that looks like it goes to Elon's profile but goes to your Mastodon instead when clicked.
(This could be used to make phishing links, sorry about that, but Twitter has had this unpatched for so long now and have been warned about this vulnerability multiple times, so they allowed this to happen.)
