Thanks for the post, great collection and info.

Just wondering if there is any tool / site out there to find out

All Existing WEBSITES for a given keyword

Say for example if I type BONVOYAGE , I want to get a list of all existing websites that either have Prefix+Bonvoyage or Bonvoyage+Suffix in the name.

Yes to get a list of existing websites that matches a given keyword, you can use one of the following services:Reverse Whois Lookup or Reverse Whois API

This is GREAT, thank you!!

I wonder how they are doing registrant monitoring now that much of the public registrant info is redacted due to GDPR.

Yes, that is a concern,but I already discoverred that Resellerclub (with reseller like Whiz.in, Alpnames and others) gives the option to opt out privacy or opt out GDPR. (you have to do that for every name).
I already called some of my countries European MP's, to warn them that the regulation has some unwanted and unexpected consequences in a "domain" they didn't exactly think about. Because there's privacy now, but not everybody WANTS privacy, certainly in this domain. The "spirit of the law" is defending privacy of the European citizen, but if they see that it can hurt a lot of companies and people they probably will listen.
But much more will have to be done to convince them in other countries too. (and I have of course still to send the ones in my country on paper and in email what's the exact problem). It are unintended consequences, of this law (theproblem with whois, I mean. That's what we have convince European MP's have to be informed about.

Yes an unintended consequence of GDPR is that it not only decreases domaining transactions, but actually impacts cyber-security in a negative way. Security researchers and law enforcement are no longer able to do their jobs effectively to catch cyber criminals.
here are several blogs on this:

Sam, can you send our support a detailed email on this, and we'll review the specifics.
thanks!
