I noticed that a lot of people are using broadband and PHP to spider sites. Since we are a BtoB site, we can look at those DSL address and we block out the last block, or what ever it is called. So if the IP is 111.222.333.444 we would deny to 111.222.333. This means that they have to log off their DSL to get a new IP, but chances are, they will still get one in the denied range. Since there are only so many providers in any given area, this seems to work well for us. But as I said we are a BtoB so when someone does visit from a DSL line, they are usually trying to learn something or research something so the few that may get blocked unintentionally do not hurt our bottom line.
