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!
I want to call out a few QoL things here that will help lemmy:
There are a lot of read-the-headline-not-the-article commenters which is natural in an aggregation feed of links; there are numerous posts a day where people rewrite the news' headlines to fit their agenda where the actual article and articles headline doesn't reflect ANY of what they're suggesting. if you run these sub lemmies for news on your server, I encourage you to use a bot or enforce rules for news that simply scrapes the title out of the link. Otherwise people will post news links that lead to a real source but have a false headline.
There is a staggering amount of people pushing for oddities like child porn acceptance and I keep seeing it. Unless an entire server is compromised, reach out to the mods and ask to get subs cleaned up. Give moderators the benefit of the doubt and a chance to act without breaking federation completely. Its important Lemmy moderates content but also communicates well amongst each other when something is going wrong.
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.)
