Gopher server attempts to start for all mix commands

I have the gopher server enabled in my config, like so:

config :pleroma, :gopher,
  enabled: true,
  ip: {127, 0, 0, 1},
  port: 7070

When I run, e.g., MIX_ENV=prod mix fix_ap_users, I see the following:

00:18:04.189 [error] Failed to start Ranch listener :gopher in :ranch_tcp:listen([ip: {127, 0, 0, 1}, port: 7070]) for reason :eaddrinuse (address already in use)

(pleroma is already running on that port. If pleroma wasn't running, it looks like gopher would start up for the duration of the task)
