Fifth Third Bank and H-BoS - Part 3

 

Just after two this morning, bank phishing scams for H-BoS stopped. But they are still continuing at the same rate for Fifth Third Bank.

I find this odd, as all the scams appear to be similar and coming from the same place. Surely, the banks are all working together to fight the spammers in which case both sets of scams would have died together.

But they didn't!

Does this mean that there is none or only a rudimentary anti-spam network amongst the banks?
