I use the plus syntax for all my logins, it'd be great to have this supported in HIBP. I have dozens (if not hundreds) of unique email addresses that I would never know may be impacted by a breach, leaving me exposed. On one hand, I'm more secure in the masses (myname+thissite@gmail.com will have a different login and password than myname+thatsite@gmail.com) so a single breach doesn't mean I need to change hundreds of passwords. But loclaly I'm less secure because I never know if myname+thissite@gmail.com was part of a breach, so my password doesn't get updated.
