As far as I see it S/RTBH is in no way a solution against smart attackers, of course it does help against all the kiddie attacks out there.
Once again, I've used S/RTBH myself and helped others use it many, many times, including to defend against attacks with shifting purported source IPs. flowspec, IDMS and other tools are very useful as well, but S/RTBH is supported on a lot of hardware, if operators choose to configure it.
It is not a panacea. It is one tool in the toolbox.
Folks can either choose to make use of it or choose not to do so; it is operationally proven, it does work, and it's certainly better than nothing. YMMV.
I agree. I think RTBH is a broadsword not a scalpel. It's a tool in the tool box and there is a danger of dropping legitimate traffic with both S/RTBH and D/RTBH. BGP isn't a security protocol. It's not even that great of a routing protocol.
