[SpamCop-List] Yahoo refusing reports and nobody is at the abuse desks?

[nobody at spamcop.net]

I tried to report a spam scammer's Yahoo e-mail address and was told 
that Yahoo doesn't accept reports to abuse at yahoo.com anymore.  That's 
not a surprise.  Every time I've reported a spammer's box, the e-mail 
address had to be near the top of the report or else Yahoo would send an 
auto-reply claiming that there was nothing that could be done because 
the spam didn't come from Yahoo.  Putting the address before the spam 
headers like SpamCop does got a reply about how Yahoo had taken 
"appropriate action" against the account, but they wouldn't say what 
action that was.  Like the inept customer service department, there's 
probably no one reading the reports.  I got an account shut down with 
only one fake report.  Make an account and put the address into some 
Yahoo message headers as the From address and Yahoo would delete the 
account after receiving the spam report without checking the IP 
addresses to make sure that the addresses were really the ones used for 
spamming and not those of an Innocent Bystander.  It looks like it's all 
automatic and run by keyword-scanning software.  If other abuse 
departments work this way, it's not surprising that spammers are able to 
stay on the same ISP for so long.  Just set up one main account and a 
second one for spamming.  The ISP will only shut down the second 
account, which is replaced within a few days and the spamming continues.  
There's a big spammer that has been able to get my personal information 
and is trying to sell me a second mortgage or a high interest rate on a 
loan or some other stuff.  The host is xo.com, which has given this 
spammer at least 5 different Web site accounts that are still working 
after many reports to this ISP.  It looked like they shut down one 
account and a new one was already up and being spamvertized within two 
hours.  Do any big abuse departments actually read spam reports and 
investigate their clients?
