# reCAPTCHA version query

 * My sister’s website has a Contact form which she wishes to protect against spammers.
 * Her developer recommends reCAPTCHA v3 because of the improved user experience
   compared with v2. However my worry is that because it relies entirely on AI it
   may be prone to false positives – and there’s no way to monitor these and unblock
   them, i.e. no equivalent to a spam email folder; so she could lose potential 
   customers without every finding out about it.
 * I realise one can reduce the risk of false positives by lowering the thresholds
   but (a) it appears to be a black art to set the thresholds optimally and (b) 
   setting them too low would defeat the object of having a reCAPTCHA in the first
   place.
 * My gut feeling is that because v2 with the “I am not a robot” checkbox forces
   the user to physically do something, it’s much less likely to be prone to false
   positives – and that it’s unlikely to be very much worse than v3 at blocking 
   real spam. And I don’t think the user experience will be much worse as long as
   users are highly unlikely to have to solve puzzles – simply clicking a checkbox
   isn’t very onerous.
 * Have I misunderstood something or am I right that given the above priorities,
   v2 is a better bet for my sister?
 * Many thanks for your help.
 * Dave

 * Hello Dave,
 * Absolutely right. I I myself prefer v2 for contact forms but had to add v2 support
   as it was requested by my users.
 * V3 is more useful when you there is human moderation required. For example user
   generated content such as comments, product reviews, etc. So if a user with low
   scores leave a review then it will be marked pending and can be approved/denied
   by moderator based in his/her judgment.
   Hope this help.Regards,Hitesh
