I heard a pretty funny story today. Back in the days of tasting one company was tasting about 200k domains a day. But once they forgot to delete them in the grace period, so they ended up with 200k rubbish domains. This error cost them a petty $1.4 mil
.
Obviously tasting has been long gone today since the grace period has been cancelled by ICANN. It is now only possible to delete 10% of new registrations in the 5 day period.
