I think anyone who allows UGC on a web app realizes that they will be targeted by SEO spam at some point. Nofollow definitely doesn't deter SEO spam efforts.

My question is, how do big platforms handle this? I thought it would make sense to put things on a separate domain, so bad reputation won't destroy the main domain.

But how can chatgpt .com/share exist then? It's on robots/allow and it's using the exact same domain that ChatGPT runs on. As I see, their search results are simply "noopener" which is super strange.

My question is, as a website owner, what strategies would you recommend for handling UGC? So far, my best idea is to buy a separate domain and let it handle it.
