I don't see it. Maybe Geo or somebody is just sending emails to people who don't ordinarily post here. For example, in another thread I mentioned Mogens paper about why you don't need RAC, and Daniel intimated not everyone has access to IOUG. So I emailed Mogens from a customer site, and he answered me including a query about how he could get involved in the debate, and I answered him, and the customers stoopid ms crap outlook server picked that moment to circumsize it's own genitals, duplicating some unique key and basically maybe losing everyone's server-based mail back to the middle of December. So I don't know if Mogens got my reply, but I do know he is interested in the thread and if he does post to that thread there will likely be a large but reasonable delay. I mean, isn't he about to host a conference with tkyte? :-)

I'm not saying there haven't been suspicious things here, I just don't necessarily see it in this case. I also agree Geo should say who he is. But hey, lots of us have online shielded identities for various reasons. Sure makes it easier to ask dumb questions! And as much as I'd like to say there aren't any dumb questions, there are some doozies :-)
