This simple Lightning DoS attack vector seems rather obvious: A Lightning node offers cheap fees, many other nodes connect to it, then it goes offline. In order to free their trapped funds, nodes have to then close their channels, which costs on-chain tx fees. Especially in a scenario with high fees this could be quite damaging.

Solutions could be some sort of reputation system for nodes, or just connecting to large, well-known nodes.
