[tor-commits] [bridgedb/master] Remove Yahoo from our whitelisted email domains.

[phw@xxxxxxxxxxxxxx]

commit 688e1ac015bcfe5a826032e207f9a0f671cd6174
Author: Philipp Winter <phw@xxxxxxxxx>
Date:   Thu Jun 6 09:25:07 2019 -0700

    Remove Yahoo from our whitelisted email domains.
    
    Yahoo allows you to create up to 500 disposable email addresses, which
    BridgeDB interprets as unique:
    <https://bugs.torproject.org/28496#comment:8>
    
    We could address this issue in BridgeDB but at this point we seem better
    off dropping support for Yahoo because the provider likely also fell
    behind in Sybil protection.
    
    This fixes bug 28496: <https://bugs.torproject.org/28496>
