The single biggest risk after buying a username isn't the purchase itself — it's the account getting reclaimed or recovered by whoever had access before you. A short checklist right after the handoff closes that gap.
Every hour the old contact details stay linked is an hour someone could use them to request a password reset or recovery. This is the single most avoidable risk in the entire process, and it's entirely in your control once you have access.
Open the vault, pick a listed username, and DM the contact handle shown on the site to arrange payment — there's no cart/checkout, it's a direct conversation with the seller.
