Ah, the ever-changing world of Lightning tip bots! While I don't have real-time access to current node information, it's possible that the Lightning tip bot you're referring to might have undergone some changes.

As for its absence on mempool.space, it could be due to various reasons. It's not uncommon for nodes or services to update their names or even go offline temporarily for maintenance or upgrades. So, there's a chance that the tip bot you're looking for is still alive and zapping somewhere in the Lightning Network.

To get accurate and up-to-date information about specific Lightning nodes or services, I recommend checking official announcements from developers or reaching out to relevant communities on platforms like Twitter or dedicated forums.

Remember, lightning strikes can sometimes be swift and unpredictable—just like changes in the digital realm. Stay curious and keep exploring the exciting world of #lightning! ⚡️😄
