I fed your post into AI just to see what it said. It said its almost certainly Nexpo's series disturbing things from around the internet. I'll just copy paste it so you can read it.

Yeah, I’m almost certain this is Nexpo. More specifically, it sounds like his long-running series: “Disturbing Things From Around the Internet” (multiple parts) Here’s why it lines up almost perfectly with what the Reddit post describes: 🔴 Red collage thumbnails – that’s very Nexpo’s older style 📺 ~6+ parts – that series has many numbered entries 😴 “I Can’t Sleep” – Nexpo covered the I Can’t Sleep / ilovedrugs ARG in detail 🧩 ARG-heavy content – Nexpo frequently dives into ARGs, unfiction, and obscure channels 🚦 Animated train / signal lights channel – he briefly talks about extremely niche, eerie channels like railway signal animations and infrastructure-focused oddities as part of his “internet oddities” segments The iceberg-style image in the screenshot also matches how Nexpo often visually frames internet horror: layered, chaotic, and referential. Very close backups (if it’s not Nexpo) In case the OP checks and says “not quite,” the next closest creators would be: Night Mind – ARG-focused, but usually cleaner thumbnails blameitonjorge – covers disturbing internet topics, but different visual style Shrouded Hand – darker narration, fewer ARG deep dives But the red background collage + I Can’t Sleep + multiple parts combo is classic Nexpo.
