There is no solid guide on how to use Monero operationally in a safe manner. Everyone will yell to churn, but there is no official information on how much and how to churn. Ringsize 5 is dangerously low. Lack of proxy support in the wallet makes using Tor much harder. Bad decisions with offline signing mean it is difficult to use a separate transaction pusher.

Ringsize dominates all because the blockchain is totally persistent but not all IPs will be recorded by every attacker.
