What kind of ācontrolā do you mean? Your posts/comments get replicated across all the other instances. You canāt really āguaranteeā a delete, since the other instances might just ignore your request for delete.
You also should be concerned about other peopleās data on your instance tho
My instance will be for me only, I will be the only person on it and it will be closed for registrations. I wonāt be responsible for anyone elseās data on my instance, nothing for me to be concerned about.
Iām not really sure about that. Iām not saying it as an expert or anything, but thatās a discussion I saw around here the other day.
Basically, once you federate and copy the content to your instance, it is in your server and you are responsible for it.
Iāll agree with a few things, tho:
It barely happens today, on centralized platforms. Theyāre hardly obliged to remove content because some judge says so (it does happen, tho, at least in my country)
Iād imagine it would be a bit of a grey area legally, right now. We would need legislation regarding the fediverse. Imagine someone posts child porn in an instance yours is federated to. Your instance copies the content. You notice and defederated the whole instance, but donāt remove the content. The dude is banned by his home instance and his post is removed. But his copy still exists in yours, since you defederated before his ban and content removal.
Just saying that selfhosting brings a lot of things that need to come to your attention.
