^ I don't think anyone really cares anymore about openly talking about stealth. There's threads about what IEM that Bob Dylan is using, etc. The days of keep stealth stealth are long gone.
Long ago, I practiced the 'keep stealth stealth' advice, but I've done a 180. To wit...
1) In my 25 years here on ts.com, I've only known of one instance, maybe 10 - 12 years ago, where a club owner cared enough about stealth tapers to come on ts.com and 'discover' what people were talking about and try to use that information to combat the run-of-the-mill stealth taper. And even in this case, there were no consequences. I think that club owner came on here a couple of times and bitched. Otherwise, I don't remember that he used any information gained here to actually ferret out and shut down stealth taping in his place. In fact, IIRC it just ended up costing him patrons because tapers ended up just staying away from his joint.
2) As discussed here many times before, it's debatable as to the illegality of ANY live music recording in an undercover manner...every situation merits its own considerations. Furthermore, for bands and venue's that allow taping, it's fair to say that it's completely OK to wear your recording rig. Lots of people simply like having taper anonymity.
3) Really, if you're good at doing it and have a small enough rig that's not going to set off the metal detectors, what difference does it make if anyone knows what our best undercover techniques are? It's kind of like if you were naked in a crowd, but invisible...nobody notices and and nobody cares.
4) Who are we kidding thinking that we're all this close-knit secret society of like-minded 'tapers' that share secrets, only amongst ourselves, over the internet that nobody else that's not a taper can figure out. As if, using a symbol like

is going to fool anyone that's trying to figure out how to keep stealth stealth. Or if someone really wanted to discover some secret decoder ring language or ours (DIN, DINa, NOS anyone?), they couldn't pose as a taper to figure out our most super secret James Bond 007 recording techniques.
5) Most of the information we share about undercover taping is just common sense. It's not like there's a whole stealth technology revolution happening and there's certainly no trade secrets being given away.
My two cents...which is always what my opinion is worth.
