The notion that these guys are actively patrolling TS in an effort to discover some carelessly posted super-secret jedi trick is hilarious.
I do think some stealth tapers have the misguided idea that security personel see stopping audience taping as a priority (in my experience they're rarely even aware of the
concept of audience taping) and that that their ability to evade detection is based on some special technique they have developed (rather than a combination of common sense and good luck).
However, and I'd be more than happy to be corrected on this point, I got the impression that much of the anti-stealth stuff on TS.com was motivated by open tapers not wanting to be tarred with the same brush as the stealthers and potentially losing the privileges they'd been granted.
FWIW, I've always thought that there is a very limited number of places you can usefully mount microphones when stealthing and similarly there aren't many places you can stash your gear when entering a venue.
Your mics/leads will be visible to audience members in your immediate vicinity and a decent pat down on the door will discover your gear. So success very much depends on good luck and simple common sense measures to avoid undue attention.
Of course, if some people prefer to think that they are secret agent jedi master outlaws, I wouldn't want to spoil their fun either.
