>if you don't have a business-tier bandwidth for uploading, you won't be wanted in most cases.
You could always use a seedbox if you want to boost your ratio.
AB is the only decent anime private tracker I know of (not that you really need it with Nyaa and Bakabat).
It's actually fairly lax compared to most trackers in that they only really care about H&R's, not ratio, so you're fine as long as you seed.
I actually do like AB over Bytes as they don't put restrictions on licensed content, like bakabt does. They also allow different sub group releases of the same show, which is good you're looking for a version Bakabt doesn't have.
