I'll try to explain what I used to do.
So I had the redirect script, which checks if the site is up or down. Upload the script on a host, and paste your phisher links there. So if say site 1 is down, it checks site 2 and so on. Ok, that's not the case, but, what you have to do is check manually the first link on the script, and if it's reported, delete it from the list, the link 2 is gona be ok for a while, and so on..
Now, to avoid the redirect link being reported, you have to buy many shortened (redirect) links for it (costs around 10$ for 1k), and make sure the redirect script is on fast host, so it doesn't show up for the victim.
That's only gona work if you spam with webmailer, where you have an option for text randomisation. So using many shortened urls is also an advantige for your spam, less chances being picked up by spam filters.
Hopefully you understood what i was trying to say

Also, the redirect script is easy to make if you know php, if you don't, find someone who does, it's not a biggie.
