I only have positive seeders on my invite list including myself, i prefer not to have anything else to keep my reputation intact.
I will trade 1 for 1 or 3 ipt for 2 danishbits as optionable for me and my family member as we're both danish.

I used to have access to most trackers, but over the years i've stuck to ipt since they have nearly everything, it's a good tracker.
