CSAM is still unfortunately an issue on Lemmy. Just yesterday I had to contact an admin of the 2nd largest instance directly to get a post removed that had been up for several hours. Worst of all, it had more upvotes than downvotes. I do applaud the admin for taking action the minute I notified them, but it should never have been able to get that far.
Also, some of the issues involving Lemmy developers really remind me of major Minecraft servers back in the day lol. There's just an inability for the "helpers" to do much problem solving because of the lack of tools, and absolute reliance on the person at the top to take action. Even then, the person at the top doesn't always have the skill set necessary to solve the issues that arise.
I look forward to seeing how Sublinks goes, but without a good reason for users to migrate it could be dead on arrival.
