They'd be foolish not to have these boads monitored for hurtful leaks, and use the info to make their damage control more effective. So, I think there are registered members here that scan for that kind of intel, but are mostly non-posting and lurkingI doubt this 100%
Maybe you're right and they don't have anyone on here. I certainly don't think they're here to id all people that may still be in the organization.
My point is that it makes alot of sense that to persuade or dissuade active dubs, you need to know the opposing points well enough to prepare a response. Scanning here is a way to keep the finger on the pulse.
If what you doubt is that they may have a couple of registered peeps....sure that may be a bit of a stretch, but then again, registration is what would allow access to most threads. So its not that far-fetched. Welcome to the board! (I'm not so paranoid as to not say hi at least).
