Antialiasing problem

Hi there,

Our website has excellent positions in Google, but we aren't presented in Yahoo.

I was told that it's so called 'antialiasing filter' or something like that.

I don't know what it is, and I'm also not sure that we really faced exactly this problem...

Let me try to explain:

The website has .com TLD
We have affiliates that have other TLD's (with our name) pointed to our .com domain...

We also have many affiliates that link to us with the affiliate parameters in links...

Can it cause the problem?

If so, what should we do?

I've reard that it's possible to contact Yahoo. Is it truth, and what email (phone #) can we contact?

Thanks.

Igor.

PS: I'd be glad to PM you the website URL if it can help

Website is not listed in Yahoo because of this
