Fandom is the darkest of cesspools. It's where entertainment goes to die and unhealthy obsessions are born.
Anyone who makes fan art, writes fan fiction, or goes so far as to take commissions on either one is the source of the cancer and should be dealt with. In the past few months someone told me to make a tumblr and that killed anime, women, and politics for me. Literally sucked all the joy out of my world. All of it. I wish they'd all just get shipped to an island with wifi that can only load cached pages. Then they'd leave us alone.
You wanna write / draw stuff for a fandom? Great. Just don't treat it like it's your job. Don't let kind words of people like you bloat your ego. Don't treat it like it's your job.
