That sounds like a disreputable practice.

While not quite as obvious, some large transit ASes, like Level3,
reset the origin to I (best) sometime between when they learn it and
when they announce it to their customers and peers.  This similarly
causes them to suck in a bit more traffic than they might otherwise.
