Seems very useful. However, I am not a fan of a subscription-based model for this sort of thing. I would hands down sign up if it was a one-time transaction. If that were the case I would also likely be a repeat customer every year.
We do see people activate the subscription for a few months, and then cancel their plan to downgrade back down to the Free Basic tier. The Free Basic tier sends ongoing Exposure Reports, so if they start to see more profiles pop back up, they re-activate. Others activate the subscription for a few months, then cancel, and then completely delete their account, and we destroy all info we have about the user at that point.
