SHAFT is carrier shorthand for a set of content categories that get text messages filtered or blocked: Sex, Hate, Alcohol, Firearms, and Tobacco. Carriers screen for these regardless of consent, and while political messaging isn't inherently a SHAFT category, campaigns can trip the filters without meaning to, especially on issues that touch firearms, alcohol, or cannabis. Here's how to stay clear.
What does SHAFT stand for?
SHAFT is Sex, Hate, Alcohol, Firearms, and Tobacco, the content categories carriers treat as high-risk and filter aggressively during 10DLC registration and through automated message screening. Adjacent categories like cannabis, CBD, and gambling get similar treatment. The point is that carriers block on content, not just sender, so a message in a flagged category can be stopped even with perfect consent and registration.
How can political messages trip SHAFT filters?
Through issue content. A campaign texting about gun policy, alcohol regulation, cannabis legalization, or tobacco taxes can use language the filters associate with the restricted categories, even though the message is legitimate political speech. The filter doesn't read intent; it reads keywords and patterns. So a message advocating on a firearms-related ballot measure might get caught by a firearms filter that was built to stop gun sales.
How do campaigns avoid getting filtered?
Write plainly, register accurately, and test issue-sensitive sends. Describe your position in clear political language rather than the promotional phrasing the filters target, register your use case correctly so the carriers understand you're a political sender, and if you're texting on a SHAFT-adjacent issue, test a send to confirm delivery before blasting the list. This is part of the broader discipline of content rules: messages that read like a legitimate campaign, not a restricted-category promotion, are the ones that land.
