How to post blocked links on facebook?

I was using free (sub)domain for my freelancing during whole pandemic and guess what - today I login to shitbook and the domain is blacklisted *rollseyes*. Can't use it in posts, comments, dms, etc. Tried to linktree it (used to post some cpa links with that in the past, it worked then) but that's blacklisted too (come on, lots of legit tiny businesses use that too, eh).

Is there any budget friendly way to cloak it or shorten it or something? Or it's time to buy a real domain and hope they won't blacklist that?

(Whoever overspammed it - thanks for fucking it up *shrugs*)
