Tbf there’s a difference. In Smallville, Clark was a teenager and Lex was already an adult when they met. And there relationship was strained pretty quickly.

There was also the history between there parents.

Smallville could’ve gone very wrong with it, but they succeeded where most would fail.

The issue with joining any new social media is that fact that its mostly fringe at the start.

I’d just try as hard as possible to train your algorithm with likes and follows on the right accounts. Not much else that can be done besides blocking.
