Is anyone willing to pay?
For the victims: DDoS is very expensive.
Direct loss of business.
Collatoral damage for edge ISPs.
Often just disconnect the victim.
Scrubbing solutions work, up to a point, for dumb attacks at lower bandwidths.
Victim bears the cost.
For the source ISPs: fairly significant costs.
Manual cleanup of bots is expensive.
Many ISPs don’t even go looking for bots on their networks.
For transit ISPs: often just more paying packets.
