We can not create any more new sign-ups

Hi,

We need to create about 380 new sign-ups on behalf of our clients.

The problem we encounter is that after registering about 35 domains for some reason your servers consider us as spam (error code AS102) and do not let us register any more from our office static IP 79.129.117.170.

Could you please advise us if there is some kind of solution.
