I have a really big site and I worry that Mollom Plus's volume limitations are not sufficient.

For very large sites, Mollom Plus' volume limit of 1,000 legitimate posts per day may not be sufficient.

For those sites, we provide Mollom Premium, our high-volume spam filtering service targeted toward large corporate and enterprise clients. Mollom Premium provides access to the same high-availability infrastructure of Mollom Plus, but extends legitimate post and correct CAPTCHA limits to 10,000 per day, each. Mollom Premium subscriptions are billed annually, and offer payment options not available to Mollom Plus subscribers.

We also provide dedicated servers and volume-based pricing for sites with needs beyond the limits of standard subscription plans.
