Hmm. Tell that to our customers, who seem to think it effective enough to purchase. :)

I think that you are not aiming for 100% automated moderation with a tool like this. Rather, you are looking to screen out the obvious stuff as quickly as you can, and then escalate the iffy content up to humans. But I speculate a bit.

Since I'm not familiar with the Cleanspeak platform, happy to set up a call with you and our sales team. My contact info is in my profile. :)
