The notification bar on android has many other uses besides when data is uploaded. Whenever vuze uploads any data it sends something to the notification bar, which in 4.3 or later only says "ads vuze data blocked". I never know what the actual message says because the android software blocks the ads messages on the notification bar.

Under the security settings any upload is considered ad, and
It usually says vuze sent 500+ads to the notification bar.

The actual notification bar becomes unreadable because every second its flipping between receiving data uploaded messages and its other functions, which makes its real function useless.
