It’s no secret that Lemmy is shaping up to be a viable alternative to Reddit. The issue it faces however is that it’s still relatively niche and not many people know about it. I propose that we change this. By contacting the mods of large subreddits and asking them to make and promote relevant Lemmy communities we could substantially increase the amount of people who discover the fediverse. What’s more, I don’t think this is would be a hard sell considering many mods are already pissed off with Reddit due to their API changes. I believe that this is the time to act, so this is a call to arms, to help grow the fediverse into the future of social media!
To your second point: possession of child porn is actually illegal in the US and many other countries.
In fact, depending on the country the instance is hosted in, it’s entirely possible that the people running an instance that hosts it could be arrested for not only possessing it (on their servers) but also distributing it (through their servers). (This is, in part, why YouTube has tried to crack down on videos that aren’t for children: they may be held liable for it.)
