The article says that after the first Vibecamp in March 2022, "both LessOnline, Manifest, and Slutcon weren’t held until years later."

That is not accurate for Manifest:

• Vibecamp’s own history page says the first Vibecamp was in March 2022 and that Vibecamp "partially inspired Manifest."
• Manifest’s official site says "Manifest started in 2023".

So Manifest began the following year, not "years later."

The rest of the chain does start later: LessOnline’s official site says 2026 is its third year (implying a first event in 2024), and SlutCon’s official site says last year was its first year (i.e. 2025). But because the sentence groups Manifest together with LessOnline and SlutCon, it inaccurately describes Manifest’s timing.
