Booksprout's freeloader prevention algorithm

When creating an ARC in Booksprout, authors can leverage data we have on reviewers to determine if they're reliable enough to participate in your ARC.

Reviewer Score

In addition to checking whether or not a reviewer has completed all of your prior ARCs, Booksprout has also added two more options (Standard and Ultra) which use our reviewer data as well as an algorithm to determine how likely a reviewer is to actually complete a new ARC. We call this their "reviewer score."

Note: reviewers must participate in a minimum number of ARCs before they get a reviewer score. Until then, we assume they are reliable.

Why prevent freeloaders based on reviewer score?

Booksprout has always given authors the ability to prevent freeloaders based on their own previous ARCs. However, as we've gotten more popular and more authors have started to create public ARCs with us to discover new reviewers, we've noticed a handful of people start to use our service to get free books. These people download books from us without any intention of ever reviewing, which is less than thrilling for authors trying to launch a book.

By selecting either the standard or ultra setting, authors can prevent those people from participating in their ARC(s) and give out less books to get more reviews.

The freeloader prevention settings


With this setting, we won't prevent anyone from participating in your ARC based on their past review history either with you or on Booksprout.


The basic setting will only consider your past ARCs when determining if a reviewer can participate. If a reviewer has an outstanding due ARC for your pen name they won't be eligible to participate until they either complete or cancel that due ARC.

Standard (recommended minimum setting for public ARCs)

The standard setting does the same check as the basic setting, but also takes into account a reviewer's "reviewer score" on Booksprout. Generally speaking, the standard setting will only allow someone to participate if they've completed at least 25% of past Booksprout ARCs. Anyone who's participated in less than 4 ARCs on Booksprout is automatically considered reliable.


The ultra setting uses the same algorithm as the Standardsetting, but is more restrictive. Generally speaking, the standard setting will only allow someone to participate if they've completed at least 50% of past Booksprout ARCs. Anyone who's participated in less than 4 ARCs on Booksprout is automatically considered reliable.

    Only just started with Booksprout and was impressed with how it got my book out - I started low with only 10 ARCs just to test it. Booksprout sent the messages but then come due date for the reviews, I only had 3 reviews! People are not reviewing and I notice that several have taken both of my ARCs...sigh...if we can manually say someone has left a review why can't we have something that says they haven't either? Sadly, I am unimpressed.

    Do any of these concerns / comments get answered ?  I've just signed up to Booksprout and feeling my way, but reading some of these comments is clearly a concern - especially if they seem to be ignored.

    Silva Hart ( [email protected] ) please block this  reviewer. She left a 4 star on Booksprout, but posted 2 stars on Amazon. She's deceitful.

    Why can't we continue to contact people who have downloaded arcs? Once the final notice is sent, we can't do anything. So we gave away a copy of the book without receiving the promise of an honest review. Feels like this service is failing authors without accountability for reviewers.

    Also, we can mark reviews as complete, but why can't we mark them as incomplete once they are past the deadlines?

    People with multiple outstanding ARCs are still allowed to download.  It appears that Booksprout's statements regarding blocking reviewers and freeloader protection for authors are all lip service and not actually implemented or enforced. Booksprout does not provide a safe environment for authors.

    Is there a way for Booksprout to block people who habitually cancel (aside from authors blocking reviewers)? In talking with another author, we've both had the same person take multiple ARCs, then cancel with an excuse about heart surgery. It is cut/paste the same message, every time, to both of us. We've both blocked her, but this appears to be someone who habitually downloads and cancels. Also, the "number of times this person has cancelled an ARC" number is zero, which is patently incorrect, and having that information be updated would be valuable for authors.

    Like writeamberanthony, I can't ask people for missing reviews, either. Can you put in a button to do that?

    What do I do about a person who has promised several (4-5) ARC reviews, but so far delivered on none of these...

    still cannot request the missing reviews. That form is not showing on a campaign from last month
