>>95897401 (OP)I get why people do it and how it can be a good thing that is mutually beneficial, but the majority of paid GMs I've seen out there are shameless con artists, running the same D&D modules a dozen times per week for randos on Roll20, asking 20USD or more per player, per session to read directly out of the Curse of Strahd book for a few hours.
GMing is thankless work, but if someone has one module or campaign book, or even just one that they wrote themselves, and they are just offering to run it over and over, for anyone who shows up, no changes made, they are just a cunt and I hope they never get to play or run any games for the rest of their lives. They don't deserve this hobby.
The ideal opposite of this would be someone charging a reasonable amount per person primarily as a way to mutually incentivize the GM to put together a good, original campaign, and for the players to be invested enough to actually pay attention, be engaged, and enjoy the game. Players are vetted and the GM is clear about the intentions of the game, it's tone, concepts, and so on. Everyone is benefited by tossing in a few bucks.
