For me, it all depends on how I come across the information. If I come across it completely independent of my employment, then it generally goes up, but if the access that I have leads me to learn of new talkgroups, then they stay in my personal list (generally).
The small handful of people who have access to my personal database can attest to the fact that there is a handful of things that I don't put into the database. My rationale comes from a handful of thought bases.
1. There are certain encrypted tactical talkgroups that I do know the user group, but choose not to submit because the knowledge of the ownership and usage, could cause a potential OpSec issue for LE. Even though it is encrypted, there are a handful of us out there who do trunking data analysis with programs like UniTrunker or Trunk88, and being able to recognize patterns through that really tell you a lot about things, even if you can't hear the voice. If my below average IQ can figure out how to run all of this stuff, then the insidious portion of our population probably can also.
2. I have done a lot of figuring out of things, and I realize that, it is time for others to learn to do the detective work involved in talkgroup identification. Although I am not privy to the list of users who submit talkgroups, I can make some educated guesses that it generally is a core group of about 10 of us. I taught myself about this stuff with the help of RR and my own research, now it is item for others to get used to it (I'm looking at you greater Minnesota). Honestly, the detective work is what I actually enjoy about this hobby, it really isn't the listening.
3. Some of my talkgroup information has been given to me by others who would prefer that it not make it into general consumption. I respect their wishes in the thought that I will continue to be able to stay in the loop.
4. I really don't like any of you all that much. (kidding)
