It’s worth noting that instances can defederate from other instances and also remove specific content even if it comes from users on other instances. Instances can also ban users on other instances from their instance.
Using an instance like lemmy.blahaj.zone is likely to be a very different (and much more supportive) experience, even if they are federated with the same instances, due to the ability for admins to curate.
I do see Lemmy.world admins take quick action when it’s raised to then. However, Lemmy does not differentiate between community and admin reports, so using the normal report function may not be enough. Lemmy.world has a separate process for when an admin needs to be contacted.
I have seen that issues raised on Lemmy.blahaj.zone get raised directly from their admin to to lemmy.world admins, and then there is swift action. Another reason blahaj is a good instance for someone who is gender diverse, the admin doesn’t hesitate to go in to bat for their members
