Monetisers get lists of expired domains daily, check their traffic and swoop without mercy. They either have accounts with domain agents or are domain resellers. In fact I suspect that many staff of domain registries moonlight as monetisers. In Australia they are a protected species and the AU domain rules were changed for them to acquire domains that were originally protected by naming rights.
