Your instance rules apply to you, so .ml, as do the instance rules of the community you’re posting on, so lemmy.world, and finally the individual community rules also apply. If you do not follow rules of third party instances it’s possible you will be banned from those instances, but if you’re okay with .ml and .world at the same time then I doubt you’d stumble upon many other issues outside of state censorship maybe as someone mentioned for Chinese instances.
