"Lemmy" isn't a website. I'm not even viewing this from a Lemmy instance, I'm on an mbin server. Do you understand how the Fediverse works? Your posts are being copied and transmitted to everyone regardless of what restrictions you claim you're putting on them, if you don't want them used that way then don't post in the first place.
And if you're finding this argument about your spam to be entertaining there's a word for that. I likely shouldn't be feeding that but this thread is already thoroughly derailed.
