Since breaches of passwords and credit card numbers are so much worse than any other breaches, it would be great if you added icons to the Pwned sites column in the report. That is it would say:

Adobe, Forbes🔑, Vodaphone💳, Zomato🔑

This allows people to focus on the most important issues first. Dates would help in this regard:

Adobe 2013, Forbes🔑2014, Vodafone💳2013, Zomato🔑2017

This isn't adding any information you don't already have, just making it more convenient.

(The emoji are 🔑 U+1F511 or🗝️ U+1F5DD and 💳 U+1F4B3.)

Thanks for providing this great service!
