Description why I should blacklist log drains is hard to understand

[wolfoo2931]

According to the description in log_drain_blacklists.html.md.erb I'm not able to fully understand the use case of the configuration.

The doppler component allows application log drains. An application developer deploying their app to Cloud Foundry can bind a drain to a log analysis service.

• Are you referring to the cf bind-service -l ... feature? I guess you do but I'm not sure.

The performance of your Cloud Foundry installation can be affected if the application developer attempts to bind a drain to an internal Cloud Foundry component.

• Why should a developer try to bind a logdrain to a Cloud Foundry component and which Cloud Foundry component would make sense to bind a drain to?
• How/Why does it affect the performance?
