Likely a combination of the community having more tech savvy individuals + realising Reddit would fuck over r/Piracy eventually, making more of them follow dbzer0 here when they were overthrown.
My understanding is that there had been an ongoing concern on /r/piracy that they would get shut down at some point, that this had been a concern in the past, and so the other stuff like the API restrictions and the rest of the spez drama was kind of just adding to the big factor pushing people away -- that the community could vanish at any time.
The lead mod on /r/piracy also set up a dedicated instance -- there was definite commitment -- made it clear that he was making the move, and was demodded on /r/piracy, so there were factors creating more inertia.
Those are all factors that did not generally exist for other communities.
IPO goals made it seem piracy days on reddit were numbered, so those with foresight were itching for a new place off reddit and leapt at the opportunity to find a new place.
I reckon it's probably a good thing we are flying under the radar in the media tbh. Media attention might draw other forms of unwanted attention. It'll be interesting to see how things shake out over the next year or so though. Those meme communities have a lot of growth potential given their demographic.
I guess Lemmy users probably also have high sympathies for digital piracy, opposing copyright is very wide spread within the open source community but there are a lot of factors at play here and I'm glad that's the case because I only started to really use it on Lemmy! :)
Putting all of the large communities on a single instance is just reddit with more steps. It's good that one of the larger Lemmy communities is not also on the largest Lemmy instance. Lemmy.world suffers a lot of outages (in part because it's so centralized), meanwhile this community remains available.
I'm subscribed to bother Lemmy communities and kbin magazines of the same name. I'm in kbin.social so I can't tell you the exact magazine name - I search for the subject, say tech, and then subscribe to all of the groups.
OH thank you! That is even more awesome. I didn't even think to look because of the name of the website has "lemmy" in it lol. This is exactly what I wanted :)
