As a permission-less network people don't need permission to do stupid things
  • Running mobile nodes for example, the intermittent connectivity means incomplete graph sync and slow startups / push-awake services cause inbound failures
  • Tor/Onion Messages, high latency and failure probability at the network layer
  • Too many channels, even people that run highly available nodes have a tendency to have channels they don't need thus bloating the graph with bad data
  • Suboptimal channels, few people optimize their channels for performance... If you're in NYC you probably don't want your first hop to be in Singapore
Granted people generally don't know this stuff and there's a lot of bad tools out there that send people down these paths, we're trying to fix that with ShockWallet and Lightning.Pub
