Your peers will sometimes pass on requests at min htl, specifically to avoid this problem. That's what the probabilistic htl thing is for. Turning off probabilistic htl only turns it off on your node; it doesn't change your peers config, obviously. So turning it off will let other people probe your store, but doesn't help you probe theirs.
