Could be, but could also be that the register terminated the domain. More
and more registers dont tolerate massive abuse but indeed its a trend. We
also noticed this. Perhaps its in advance, we have also seen that. They
assume some part will read the mail later. Would be nice to watch those
domains if they come alive lateron this week or so ?
