“data” is a very open ended term so it’s not super clear what you mean. It’s also a bit unclear because I don’t see why that’s especially true in this particular case. I take it you are saying some sort of precautions should be in place to stop bots from running rampant. And sure, that’s fair enough. I think that’s true of all of lemmy and any activitypub project though, and will depend on how they handle moderating.

Is there any reason you think a site focused specifically on 5+ year old content is uniquely vulnerable to spam bots?
