It's perfectly possible to do but they obviously CBA. Anyone can register themselves as a travel agent, bot buy months-worth of timed entry tickets and sell them on Viator and getyourguide for 4x face value, or more, as so called "skip the line". The latest racket they've uncovered at the Louvre was going on for ten years. I personally decided to stop going to Italy a couple of years ago because I was so sick of all this nonsense every time I wanted to visit a gallery or museum, it's such a time consuming pita to navigate. But it's a problem across Europe, because the venues set up these systems where the only way you can get in is to book online but at the same time their security is so shit they leave themselves wide open to bot buying or possibly even collude with the bot buyers. There are huge web platforms dedicated to this kind of resale and for at least the last decade but especially since covid when everything went online and timed entry it has made accessing culture and art costly and frustrating.
