If the user privacy does not matter on your site this extension may be quite useful for custom profile types since you can set up almost everything for each profile type. But do not expect any support on this extension, the developers seem to not like responding to e-mails.
Thanks for sharing your concerns.
EMail support is really tough as it cannot be tracked. Therefore we ask every time to post over forum for fast and timely response.
Regarding the privacy concern, JSPT is used to control the access of users(by ACL rules). So if you want to freely allow users to set their privacy as per field, then there is no issue, you can do it for all fields. But for selective fields it will not work until the next version 3.2 is released.
Anyways thanks for posting review, hope to see you over the forum to resolve the issue you had.
