Re: major sponsor of spammers refuses to accept email at abuse

I also just want to make clear that there is nothing personal going on
neither from my side.

BTW, I tried to answer this directly to you, but as you block the whole
200/8, it was not possible.
Interestingly, this could be your your first "ham" message from LACNIC
region. Not this time... :(

I sent my message to the list just to make it clear that not everyone
in LACNIC region is spammer.

The way you said the following:

| Behind all of LACNIC's 200/8 and Iskimaro, whoever the heck they are!

sounded that you had no idea what LACNIC is, and don't even care. 
To you it is just a bunch of spammer.

Other might had the wrong impression that really doesn't matter
what LACNIC is, and start to block the 200/8 because someone does so.

Just my thoughts,

| I certainly do filter abuseive asian networks, except for networks
| that my users need connectivity to, or networks that I have not seen
| abuse from:
| I think you'll see that there's no region singled out there. You might

| I'm sorry if my actions have offended you, because there really is
| nothing personal going on here, just pragmatism and a desire to
| prevent as much spam as possible from reaching my users.
