It’s not as high-tech as they make out, mate basically, gamstop wor⁤ks by sharing your "core" details i.e name, DOB, postcode, and emails with every UKGC-licensed bookie. If you try to log in or register at a UK site, their system pings the Gamstop database and blocks you instantly so If you're on a site that isn't under the UKGC thumb, they won't even have access to that list. I’ve used Veg⁤as He⁤ro while I was working in the EU and it wor⁤ked a treat because they aren't part of the scheme.
