Right, that's one of the risks; then there are others, for example imagine the list non being mantained, an IP (now clean) gets blocked since it was not removed from the list; also, since in SORBS case the list is "on sale" before trusting it again it would be a good idea knowing "who" will buy it and then make a decision |
