Most software that automates Facebook actions has you login through a Facebook App, meaning you can disable access to that App through Facebook. WhiteHatBox's FollowingLike takes your credentials directly and uses them, not going through Facebook's App interface. I confirmed this with their support team. This means that once they have your credentials, you can never disable access from that App until you change your credentials.
This is a non-standard and uncontrolled use of Facebook credentials that consumers should be warned against using, especially in this day and age. When I notified WhiteHatBox of this and asked for a refund, they would not give me one, offering only 50% back and other free software, which I certainly do not want given their philosophy on using user credentials.
