Some aggregators don't accept links to rss, but I also don't like the idea of having the rss feeds on the same ip as money site so hosted them on cheap autoblog site on another hosting to my money site... Works well.
Ps. I use sbox to make the feeds
When you use sbox to make the feeds that means each feed is created with a different IP?
How many links do you put in per feed?
Is anyone actually going to the extent of creating different email accounts and ip's for each feed? I am debating whether to do this or not. Sure it will take a shitload of time but if the results are there then it might not be a bad idea.
