Yeah, they ignore SF311 reports by policy. I've managed it by flagging down an amazingly helpful parking control officer that happened to be in the area, or else by calling and reporting an obstruction of traffic (not mentioning the bike lane) and then waiting until the PCO arrived and talking to them.
The officers have almost always been helpful, but I think they generally tend towards lower confrontation and more "efficient" violations like street sweeping or expired meters by default (or perhaps directed by management).
