When a contact adds me to their list (yahoo protocol) I get a notification in the system tray widget. Trying to deny that request only postpones it until next login. I suspect the request is a spam. (happens often in yahoo messenger)

Reproducible: Always

Steps to Reproduce:
1. ask someone to add you to their list (yahoo protocol)
2. when notification appears, deny the request
3. log out and log in again
Actual Results:  
The request keeps coming up at every login (ever different computers, when I login with the same account)

Expected Results:  
The request denial to be recorded and never see that request again.
