I hope you learned your lesson and do not run a public node anymore.
Run private nodes if you are not well prepared for public ones.
I wrote so many guides about these aspects:

- https://darthcoin.substack.com/p/managing-lightning-node-liquidity
- https://darthcoin.substack.com/p/lightning-node-maintenance

Of course I saved it, just now when I'm a bit paranoid I would like to double check it :)
