My problem isn't with the tag as much as it's with the "free money" for flying through a system I've never been before. I sometimes make more money running missions, not from the mission itself (delivering data or cargo) but because I "discovered" the ELW in the Bubble that the destination station orbits. The RL equivalent is running a shipment in my truck down to a city I've never been to before, bringing back a tourist pamphlet from said city, and being paid more for showing the boss that pamphlet than he paid me for running the shipment! It's utter nonsense, and I hate "nonsense" in immersive games like Elite.I only thought you get the tag if you sell the data, or am I wrong? In which case, don't sell the data and you won't have to deal with the tag.
As for not selling the data, well you got your answer from the other posters.
