[@BrokenPromise] hit some good beats. Here are some more:

1. It's the GM's story, not yours. You can participate in it as it is, or you can make suggestions to the GM in the hopes that he'll change something. Or you can leave. He doesn't owe you anything, so don't be mad if your attempts at backseat-GMing aren't well-received.

2. A GM can kick you anytime he likes. He doesn't need a reason (although he probably has a pretty good one anyway). If it's clear you're unwelcome in a thread, take the hint. Arguing, flaming, or trolling will only prove him right about you.

3. The GM's job is to draw the blueprints, not to singlehandedly build the house. If you're not willing to actively participate in designing the plot, if you're "just along for the ride," if you and your character offer nothing to the group dynamic, then don't sign up. First it's a sign that you'll get bored easily and quit sooner than the other players (since you have no emotional investment in the story), and second, the story will be fucked when the GM is gone due to vacations or sickness or whatever, because none of the thread's player-base will have the chops to keep it running until he returns.

4. Embrace spontaneity and change. The character who either never grows and matures at all, or who does so according to a pre-written script, is just as damaging to an RP as a GM who "railroads," forcing the plot in the direction he likes because improvisation is [i]haaard[/i].

5. And here's one for my fellow GMs, for fairness's sake: the incentive you give to a player to read your thread is called a "[url=https://www.time4writing.com/learning-how-to-write/starting-with-a-hook/]hook[/url]." The hook begins with the title, and it ends with the introductory paragraph. If I know what your RP is about just from reading the title, you have failed to create an intriguing and engaging hook, and doubly so if, when writing a genre piece (Western, Sci Fi, Horror,...), you have done nothing to add anything interesting to the genre. We know all the tropes by now. Dare to be daring.
