I know edoro has made a lot of posts about this on his tumblr and is probably the first truly Beluzpilled user. It's funny-- back when I was first getting into the show, a mutual would send me a lot of his meta posts about Belos being a pedofreak, as seeing the obvious Rape Coding while staying on the normal side of the TOH fandom was making me feel insane. I know most stuff revolves around empgold-- I called that shit months before I even watched the show-- but the moment that truly convinced me he was a freak for Luz to was the way he said "Luzura" in Hollow Mind. GET AWAY!!! FREAK!!! The rest of the scene is literally insane for obvious reasons.

Honestly, if Luz was a little older I think we would see a looooooot more Beluz content, similar to Darklina and other dark hero/villain YA ships. I'm sure there are a ton of people who pick up on this, though, and just don't feel comfortable saying it. Most of the show's fandom seems to have come from lumity, which is fine, but the prioritization of the canon wlw ship and the heavy presence of antis in this fandom makes consciously acknowledging these parts of the text difficult. If TOH were a YA fantasy book series there would 1000000000% be more explicit sexual tension between them, or at least an open acknowledgment that Belos wants to fuck her. No one argue with me because I'm right.
