Given how unstable Lemmy's performance is, adding even more incoming activity is likely to cause more crashes and problems. And it isn't as if there are aren't 1200 other Lemmy instances out there who are showing content from Lemmy.world
I remember when Beehaw's signup code in Lemmy was so broken that there was a huge backlog.
It seems to me that Lemmy overall has slowed down a lot,
That's helped with the crashes in recent weeks, less data, less crashing. Lemmy.world has over 9000 communities, moderating all those entrances is huge, and the SQL performance problems in Lemmy are aggravated by all that additional data.
