I'm not sure that anyone ever actually lost any data, but the potential for that ever happening should be over by now. Likewise, I don't think there's any danger of posting or subscribing too much overtaxing anything.
Thanks for choosing piefed.social for your community's home. Your post on !newcommunities@lemmy.world made more people aware of PieFed (and prompted rglullis to add it to the https://fediverser.network/ thingy) so that was good to see!
