Match UK reviews are under match.uk
Go over to reviews under match.uk to see reviews on the UK version of Match. As you may not know, the Match Group has a monopoly and own every dating platform you may know, so check out the Trustpilot reviews for their other platforms such as Tinder, Plenty of FIsh, se.match.com (Swedish version of Match), match.no (Norwegian version of Match), etc.
Remember, if you are unfortunate enough to join Match UK, you will (excluding the scammers) should only be seeing UK-based. Match Group runs separate sites (and apps) for other regions such as Match USA.
A lot of the fraudulent profiles you see on Match UK were written towards the Match USA site, so this will be a clue. The fraudulent profiles also can jump around locations, so one moment they are in London and the next view of the profile they're in Paris.
