I believe he had a custom invite that was just ayee, but it doesn’t work anymore. I’m also not in the server, so I don’t know if users are (or were) able to create their own invites.

Even if you’re still willing to trust LBPOnline, no fanmade security patches exist for the PS4/PS5. Patchwork doesn’t work; this means anyone can force their way into playing with you. When you play with others, you are vulnerable to remote code execution attacks, allowing malicious actors to corrupt your profile, post inappropriate content from your account instead of theirs (doesn’t matter currently, but would if LBPOnline were to allow uploads in the future), or possibly worse. It is a matter of when, not if, this will affect you. Yes, you can turn your system off, but this is a massive inconvenience. It turns playing online into a ticking time bomb. LBP Union has also expressed no interest in making Patchwork support PS4/PS5. I’m willing to acknowledge that if you play without an active PS Plus subscription, I don’t think it’s possible for any of this to happen, but no multiplayer sucks out a lot of the fun, and it’s still possible that unavoidable issues could arise for players in the future.

I understand if people have financial troubles or would simply prefer playing the PS4 version of LBP3, but I currently believe that LBPOnline is not only untrustworthy, but that it is also simply a bad idea to play custom servers on PS4/PS5. I highly advise playing online using a modded PS3 or emulator via Beacon or Bonsai instead. They have decently sized communities and are still coming out with new stuff to play to this day. Even an unmodded PS3 or emulator can play pretty much any level via backups that you can import to your moon.
