Spamhaus has very recently been restricting usage of their servers. The actual
statement by them is if you have more than 100 users, you need a datafeed.

A lot of this has to do with things like Barracuda boxes, which use spamhaus by
default. Barracuda and other "spam appliance" companies have made and sold so
many of these boxes to larger organizations without using a datafeed that it is
beginning to swamp the spamhaus DNS servers.

AFAIK, Spamhaus is now using an automated rate-of-query analysis to detect
servers which are maintaining a high rate of queries over a long period of time.
Those sites are automatically blacklisted to cut load.
