I should perhaps lead with the caveat that I am a very private person. I prefer places like Second Life and craigslist, which have solid privacy policies, over Facebook and Twitter, for example.
I have posted the location and linked to the most likely script in the tracker in my posts above.
Someone IM'd me inworld and said they thought trackers were allowed. As I cut'n'pasted from the bylaws above, they are allowed, but only in specific instances - so they are allowed but in a defined, limited capacity, i.e. in commercial parcels for commercial applications.
I know from my own experience, I used to have a visitors log for my shop which I used for very specific purposes - I wanted to know if anyone is coming because I was just starting out. I needed to know names because I want to differentiate between my own time in the shop, friends that stopped by to say hello, group members of my store group, and new customers -- all for the purpose of knowing if my shop had a chance of becoming a going concern or if I just had pretty prims on an empty parcel.
I don't have a tracker anymore because my shop has generated enough overall traffic that I measure my success by actual sales now. However, I've been helping other people grow their own businesses through improving how they show up in search and I am using a tracker at their places for the same reasons - getting from zero to "x". So I know they have legitimate uses.
As a customer, I expect to be tracked by the shopkeeper and I don't mind.
As a CDS citizen, however, I definitely DO mind, especially if the use is not codified but is just someone tracking visitors to certain areas on public lands without any Constitutionally defined reason or oversight.
It is possible the citizenry decides they WANT to track avatars, perhaps thinking they want to do a follow-up IM, and if people want that, it should be put to a vote and made public. That is something I would vote against as I'm the kind of person who wants to check a place out and then, if I'm interested, go find someone to talk to. We already have an that kind of system set up, with the touch-notecards at the Info Hubs. I would find a CDS representative IM'ing me just because I visited the sim really creepy. But that's just me.
