Unsolicited commercial e-mail, aka UCE or spam,
has been a growing problem for users of the Internet. Thousands
of such messages are sent to our systems every single day, clogging
our customers' mail boxes with useless, and frequently offensive,
junk e-mail. Not only is it irritating, but it is insidious: it
costs ISPs uncountable sums as they are forced to lend their resources
and overloaded systems for the delivery of those unrequested, unwanted
messages. It is 'postage due' marketing, just as if a telemarketer
calls your home collect. Because these "online marketers"
can send their messages so cheaply, with nearly all of the cost
pushed onto the unwitting recipients, the volume of spam has been
We have received many requests from our subscribers
asking that we help them block out these types of messages. There
is no perfect solution to the problem, but in an effort to reduce
the amount of such mail that our customers receive, we have adopted
some strong anti-spam measures. They are applied across the board
to all users of e-mail at aloha.net, but customers may easily opt
out of the filtering service.
In essense, we subscribe to services which allow
us to deny all e-mail sent from Internet providers who have repeatedly
demonstrated their support of spammers. Providers only make it onto
these "blacklists" after they have demonstrated such behavior
multiple times, have been contacted about it, and have not changed
their ways, continuing to allow spammers onto the Internet through
their networks. Any responsible ISP will not tolerate such behavior
from customers and thus will not end up on these blacklists.
