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.
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.
