With threads coming to the Fidiverse, I feel dirty and violated.
I don't care about my posts being accessible from various instances, but I fucking don't want meta to use what I write, from my username to my subbed communites and such.
I leave in Europe where the app is not allowed right now. How can I protect myself from meta ?
Edit: I tried writing out an explanation of how defederation works, but Lemmy has a few more gotchas with communities being owned on different instances. See https://lemmy.world/comment/276067 for some info about how the Beehaw defederation of LW worked.
Meta can and already probably does have crawler bots capturing the data anyway. Anything public on the internet you should assume is consumable by these types of companies.
Additionally, instances of ActivityPub platforms can further require releases of ownership if they have a TOS stating so in their registration (like any other website). IANAL but I would reach out to one to discuss your options on restricting the usage of your works if that is a concern. In general, I think the safest option is to host your own works and share only the links and what you don't mind being scraped on sites like these. Some AP platforms like Mastodon Glitch Edition allow local-only (non-federated) posts, but as far as I know Lemmy don't support that yet.
