藍勾勾推特官方服務中心稱為The blue Verified badge,國外常常以Twitter blue check mark或Twitter’s Blue Checkmark作為代稱。藍勾勾是具平台方認證為真實性、可信任的品牌標誌。藍勾勾通常由品牌方、知名人士、運動員、政治人物、新聞工作者、具影響力創作者所取得,明確將藍勾勾用戶與一般用戶做出區隔。
Twitter does not sell the blue Verification badge. A Twitter employee will never request financial compensation in exchange for a badge or as part of the application process. Twitter does not authorize any external agents or individuals to sell Verification on the platform. We encourage people to directly apply through the Verification application process available in the Twitter app. Individuals offering to buy or sell Verification are subject to loss of Verified status and permanent suspension from the platform.
