Neat trick. Firefox does give a warning about it:

> You are about to log in to the site “i-dont-have-linkedin.com” with the username “linkedin.com”, but the web site does not require authentication. This may be an attempt to trick you.

> Is “i-dont-have-linkedin.com” the site you want to visit?

If those sites are even more clever than a regex, they might bin your application for this.

What kind of HR writes scripts to check for weird URLs in people's links

They're orders of magnitude more likely to bin your application for a thousand arbitrary reasons than to have specifically implemented something that weird

You shouldn't live your life around things that will likely never happen
