Most of the admins' replies on the limit was "it is too hard to configure for non-default, and it reverts back to default after each upgrade", which to me if it was true, sounds like a packaging issue or inablility to oonfigure the build (with rust I wouldn't be surprised). Maybe they are running mastodon on windows, who knows, so to engage in /etc/ configuration is pointless.
I am not a server owner because I can't afford it. I am simply a user.
