A German Valorant player just got hit with the ultimate hardware betrayal: their shiny new used Ryzen 7 5800X3D came pre-loaded with someone else's Vanguard hardware ban. They bought the chip on Kleinanzeigen in late September, dropped it in, launched the game, and got booted instantly—no matches, no chance to prove themselves clean. Riot support confirmed the CPU ID was blacklisted since August 12 after the previous owner cheated, and the buyer claims swapping parts won't fix it because the rest of the rig got tainted too.

Vanguard's fingerprinting doesn't mess around—it tags individual components like the CPU's TPM, and this case shows how that sticks even after resale. The player is stuck unless they build a whole new rig, and there's no public way to check a used part before purchase. It's a brutal reminder that secondhand hardware carries invisible scars from the last user, especially in a game this sweaty.

Riot's anti-cheat lead Phillip Koskinas pushed back on X, saying hardware bans max out at four months, don't spread to every component, and he couldn't find a matching support ticket—making the full story "pretty unlikely." Still, the ban wave hit hard enough that the buyer is warning others: test that CPU before the return window closes or kiss your ranked grind goodbye.

This isn't just one unlucky guy; it's a systemic headache for the used PC market where no ban registry exists and buyers eat the risk. Cheaters sell their gear to move on, and honest players pay the price when Vanguard doesn't care whose hands are on the keyboard now.
