“Sounds like you don’t understand what’s going on – please educate yourself.
4chan is being SYN flooded, various ISPs were getting a lot of collateral traffic from the resulting ACKs going back to spoofed IPs. Since those ISPs had nothing to do with either the attacker or 4chan, there was nothing they could do but pull the plug on the source of the collateral ACKs (4chan). i.e. the ISPs who blocked 4chan weren’t trying to protect 4chan from an attack, they were protecting their own networks from the fallout.
Sadly, like you, the vast majority of users are clueless and won’t investigate to see what is only going on. I’m sure there will be a kneejerk reaction against AT&T and the other ISPs who tried to protect themselves and everyone will make out that they are the bad guys.”
