There are tools out there that help with this, but the better ones like the one I linked use the API.
I don’t know what will happen to them next month, but if you are thinking about it, keep in mind that they may not be around or work like they do today, and you may have to use other more convoluted tools.
For now I am holding off on deleting everything, I don’t think I will ever go back (Lemmy is so much better) but I do want to wait to see the outcome of it going dark before I decide to remove all of my posts & comments.
