Me too, but I wouldn't trust someone to necessarily tell me about previous encounters with airline corporate security departments.
BTW, DL requires a FF number for someone to be eligible for a (free) upgrade as the traveling companion of an elite, but I've never klooked carefully at the rules regarding needing a FF number or not for an instrument supported upgrade. [Under certain conditions, an expensive ticket for a DL flight can be upgraded using certain partner airline's FF program miles, which should in principle still work after one is banned from participating in DL's FF program.] OTOH DL rules permit gifting of SWU-equivalents only to someone (one person only) on the same flights as the elite, which makes it virtually impossible for someone to attempt to sell these upgrade instruments. I like this.
