Based on my research, I can verify this claim with important context:

Verification:

• The Epstein Files did reveal that Jeffrey Epstein used the username "littlestjeff1" on YouTube, where he purchased Alfred Hitchcock's film "Frenzy" in October 2014¹²³
• However, the Epstein Files do NOT show Epstein used this username on Fortnite. The Fortnite account with the username "littlestjeff1" was a hoax by another user⁴¹²³⁵
• According to Epic Games (Fortnite's developer), an existing Fortnite player changed their username to "littlestjeff1" after Epstein's YouTube username was revealed in the files - the account originally had a "totally unrelated" name²¹⁵
• Epic Games explicitly stated: "We have no record of the subject's email addresses referenced in the public document existing in the Epic account system"²
• The claim likely stems from confusion about a $25.95 email reference to "VBucks" in the files, but this email has redacted sender/recipient information and is not confirmed to be linked to Epstein²³

Overall validity: 30%

The username "littlestjeff1" was indeed found in the Epstein Files, but for YouTube, not Fortnite. The Fortnite connection was a deliberate hoax by a troll who renamed their account after the files were released.
