-Edwin-, I will try to address what you said without getting too specific about some matters.
CAPTCHA is used to deal with automation and the problems that can be caused. Among other things, it is used to deal with spammers and to abuse of resources.
There are a lot of bad people in this world who want to do bad things and it is just necessary to try to make things more difficult for them. The more "user friendly" that you mentioned would make it a lot easier for automated software to gain access, and that is something we don't want to happen.
With the issue you raised, without CAPTCHA it would be easier for automated software to make thousands upon thousands of searches for no reason at all other than to try to cause problems. It would also make it easier for the posting of automated spam as well as several other problems.
A few weeks ago I had to make the CAPTCHA stronger (more sophisticated) in order to deal with some problems we were having. If we were to make it weaker, the main thing that would happen is that it would make it easier for automated software to try to create headaches in the form of much more spam and other matters that I don't care to get into.
If you are logged in you won't need to deal with CAPTCHA when doing searches. We have methods in place, other than CAPTCHA, to reduce seach abuse by logged in members. You won't have any problems conducting your searches if you are logged in and you won't need to deal with CAPTCHA.
CAPTCHA needs to be strong in order to make it possible for you and all of our members to enjoy 5 Star as much as possible without having to experience the potential problems that would be present with weaker CAPTCHA or no CAPTCHA at all.
