Hmm.. Interesting.. going to give it a try.
I've discovered a a company that are giving away 1000 link credits as a free 30 day trial membership, my trial is just about to run out but so far i've managed to link to over 300 websites all over pr1 - pr4 (cost per link depends on targets PR)
have a look, there's no payment details needed for your trail. Its helped me and can hopefully help you.
The user tryed to hide his affiliate link with url tags.. So his "trial" membership is bull*hit
