Comment (by phw):

 I learned from a researcher that Yahoo lets you create up to 500
 disposable email addresses, which are intended for third-party
 newsletters:

 BridgeDB interprets these disposable addresses as unique users, which
 makes it easy for an attacker to get a disproportionately large number of
 bridges. We could teach BridgeDB to recognise disposable Yahoo addresses
 but at this point the better way forward may be to just disable Yahoo
 altogether.
