Some are adventurers; some are regular citizens of the galaxy; and then there are the really complicated ones.
Every government in the Galaxy has a different policy on information about its citizens. Additionally, every department of each government has a different system for what data they collect and how they format it.
No well-traveled citizen of the Galaxy has the time and the resources to trawl through all these different systems on a day-to-day basis -- not even with droids dedicated to the purpose.
The BountyPedia started as a haphazard conglomeration of data which the Bounty Hunter Guild threw together from easily accessible data on the HoloNet. The information listed in a bounty about the target and known associates was an obvious point of contribution; then members started to add information about ancilliary contacts: helpful bartenders at the cantinas of Spacer's Row, obstructive bureaucrats at Starport Authority office of a given Sector, which merchants sell what quality of quasi-legal weapons and ammunition, who among these merchants will then sell the information about what the bounty hunter wanted, who is worth talking to, who is a waste of a bounty hunter's time.
As more (highly subjective) information got dumped into this database, it became more unwieldy. Eventually the leadership of the BHG decided to put a few restrictions in place:
In the past several centuries, use of the BountyPedia has become so commonplace even among people who are not bounty hunters that the Guild created a separate Guild membership tier just for "junior contributor" access to it. This is not a cheaper membership than being an actual bounty hunter. Hence the duplication of some BountyPedia data on the HoloNet in general: but it takes time for updated information to be propagated through all the HoloNet hubs across the Galaxy.
Any character writeup in this section with the words "TEST CASE" in their summary are for testing and practicing as the gaming group learns how World Anvil works. Find something weird? Tell Rissa about it via the handy Google Sheets thing. Most of Jedi Quest also exists for exploratory messing around.
