Yes. Peers NEED to check in with the tracker at the interval defined by
the tracker (do NOT use an arbitrary amount of time) or else you won't
get new peers connecting to you.

Because ISPs have created conditions where the supposedly smarter peer
selection creates much worse performance overall, and as such the
implementations aren't actually smarter.

The only real selection improvement that actually helps right now is to
not give seeds out to other seeds.
