Trusted Domain Market Place Or Creation

Hey, Ive been trying to redirect through a bio in a social network recently but all the domains I purchase get me banned. I tasted a domain I had for a personal page that has some traffic (20 views daily) and that was registered on oct 2023, and it worked. Apparently the platform only allows "trusted domains" so Ive finded out that if the domain is present on similar web, then it will probably work. The thing is that I'm not really sure how I make my personal page a "trusted domain". I wanted to ask if you know any marketplace to buy this domains or how to create them efficiently. I forgot to mention that the use of link shorteners and "linktree" alternatives are blacklisted.
