It is a Security device to see if the entity trying to access the feature is a person or a robot. However, most CAPCHA's use a seris of distorted letters that most persons would have so much trouble readin that it would take a number of tries and the person may give up. As an alternative, they present an audio clip that says the letters in such a garbled way and with so much interference that only those with the best of hearing could understand them. In either case, there are or probably will be, robots that will be able to read or hear them Ours relies on the ability to read images and use some intelligence. It uses pictures of very common items at RLFFELS & RIBBONS GIRLS' HOME with the name underneath. The name, however has only the first and last letter of each word and you must enter the full name of the itme in the input box. This does 3 things 1, most robots cannot read images. 2. If one that can comes here, it will need to figure out the missing letters. A Little Boy does not know enough about what is here to figure out the missing letters. 3. Even if the robot could read the images, it could not decide which one to pick
The net effect is that this capcha and most of our pages that use image identification are about 98% spmabot proof. There are robots that can read images but they are too costly and slow for all but a very few spammers who would go after rich suckers or fairly large busiensses and for whom a non-paysite would be slim pickings and not worth it. The crooks work on a units/time/cost basis. it is better to get 10,000 addresses in 10 seconds at a cost of $400 than 15,00 in 20 seconds at $400, 10,000 in 5 seconds at $800 or 15,000 in 10 seconds at $900. The login pages of which there are two in LittleGirlLand and one other, are about 50% secure themselves, and would require a human who is bound and determined. Even if he were to get into members area. our presentation of email address use both text and images with the crucial parts being images so that is 98% spambot proof and a human would have to input each address directly into his mailer rather than click on or read them electronically. This is more work than a spammer would care to go through for the results he would get. Even if he did that then, if you did as you are told and used a webmail. he would have to deal with your spam and virus protection, then your browser defenses and finally your local defenses. Now a skilled person can get through but it would not be worth the effort and these are few and far between so it is reasonable to think that all, told, you are about 96% secure. This is accomplished by multiple layers and is about as good as it gets short of professional paid defenses and they only get about 98%. You are far more likely to be successfully attacked from some other place and account than here and since you have no account here and almost no electronic presence, this is a dead end. Hopefully any accounts that you use that can be traced from here are reasonably protected
