The problem is that they are spoofing our IP, to millions of IP's running port 80.
Making upstream providers filter it is quite difficult, i don't know all the upstream providers are used. 

The main problem is honestly services that reports SYN_RECV as Port Flood, but there isn't much one can do about 
misconfigured firewalls.I am sure there is a decent amount of honeypots on the internet acting the same way, resulting 
us (the victims of the attack) getting blacklisted for 'sending' attacks.

And even if his network weren't on the receiving end of a reflection/amplification attack, OP could still see 
backscatter, as Jared indicated. 

In point of fact, if the traffic was low-volume, this might in fact be what he was seeing.
