Can you add also the valve system, as described by Rene Pickhardt ?

Interesting posts!

AcceptLND is just a gate for new incoming channels, it doesn't modify any policies or take any actions of that kind.

However, I have another project called Hydrus that does something similar. I didn't implement the algorithm Rene proposes, but I took a more simplistic approach, which is updating the max HTLC value to 80% the local balance to avoid routing failures and to leave some room until the next update.

I would say higher fees is a better protection against drainage though, the other node could still drain all your liquidity with smaller payments.
