For example, I'm making a desert / hellscape / lava racetrack map pack, which was requested by a DM running Descent into Averness, but I'm tentatively just calling it "Rocky Racers" and obviously people who are playing that campaign know what it's useful for, but it could be used by anyone running any game where a racetrack would be useful. I don't have permission to call it "Descent into Averness racetrack". Now, there is one place where this isn't true: the DM's Guild... they have a specific arrangement with Wizards of the Coast. But on Roll20, no, you can't namedrop a specific adventure, even if your pack would obviously be useful for a specific adventure. That doesn't mean you shouldn't theme a pack to suit a specific adventure, you just can't legally use its name as part of your name. Anyway, it's better to make it a bit generic because of the wide variety of games out there. People who are running the adventure will know what it's good for, and people who aren't won't feel they can't use it for their off-brand non DnD Fate Core game with their own monster rules that just happens to use the same monsters as the set you made. By NOT saying 'it's for THIS adventure' anyone will feel like they can use it in any campaign and setting if appropriate. :) So it works out for you better that way... or for me... to just say 'this is a lava racetrack, this is a desert racetrack, this is a rocky terrain track, they all loop around' instead of 'you can only use this if you're playing DoA'.
