So should you avoid having kids with someone you look similar too then? Like is it that the virtual twins have genetic similarities akin to 3rd cousins or siblings...

Thats plain rediculous. How can I possibly find someone good enough looking then?

This is why my sister and I always use protection.

I mean, iirc there’s no genetic reason first cousins shouldn’t have kids, I doubt third cousins would be a problem.

First cousins not having kids is generally good since it prevents the founder effect from getting too bad or long term inbreeding like with Charles of Spain or really any European royal.
