Comment:

 > It seems like you disclose some information fetched from bridges.tpo,
 please don't do that.

 Why? It's easy for everyone to download some bridges' addresses, look at
 them, spot common subnets and create just 3 firewall rules to block most
 of them, even unknown? Its not a bug, its a vuln!

 > If bridge got blocked you can to request new one.

 How can I request a new one if TPO websites are blocked? And what if I
 request a new one and would be given the new one already blocked?
