There’s no way to effectively protest a corporation on its own platform. It controls the platform, it can and will change the rules or enforce them unequally just to shut you up, and there’s nothing you can do about it.

You can still make it painful for them on the way out. They are using up a shitload of resources dealing with this, and it will be hurting their image and valuation. The more Reddit has to stomp on its users, the more damage they do to their brand in the long run.

You can't win, but you can go down fighting, and possibly take Reddit down with you.
