Okay, as someone who doesn't know anything about both sites, a casual test (surveying results for Toronto, ON) does not suggest any data was lifted off your site. In fact, there is just one entry for all of Toronto on Bedbug Registry, whereas Bedbug Lookup seems to have dozens.

Of course it's possible that your search simply doesn't work, there are copious error messages on Bedbug Registry... Can you give more details about what you think was scraped from you?

At most BedbugLookup seems to be a superset of your site data.

Edit: seems the search on BBR is not working for me (and apparently for me only). Thanks for providing the links, I see that the data was indeed scraped. Not cool.
