You can try a domain history site, or a site that contains past WHOIS information, to get as close as you can to the domain owner.
There doesn’t appear to be any way to access the most current domain owner info after the GDPR (since it would be a privacy violation), but this will at least show you the most recent owner before the information became private.
A number of websites offer archives of past WHOIS information, leading up to when the GDPR went into effect. (You’ll need to pay to access info on any of these sites.) Your options include:
You can also try DailyDomainDetail.com, which promises to give you a list of WHOIS records while leaving out the ones with the info hidden for privacy. Alternatively, try Googling for email addresses “@domainname” - often, an owner will have registered an email address to go with the domain.
You could even try checking Wayback Machine for old versions of the webpage that have visible contact information, although that’s a long shot.
Other tactics, like offering to buy the site, can also get you in contact with the domain owner, but probably aren’t ideal for your purposes.
Unfortunately, there is no longer an easy “trick” for getting this information post-GDPR, and you’ll have to decide whether paying to access historical WHOIS info is worthwhile or not.
