Most captchas are on websites where you have to create an account for something. Are captchas preventing some kind of automation scripts that create multiple accounts on a website?
What are some other reasons that captchas exist?

Yep. With no CAPTCHA, anything a human can do on a website, a bot can do.
Common kinds of automated abuse are:
– Registering lots of accounts
– Creating lots of spammy posts, DM’s, etc.
– Trying lots of common passwords to steal an account
– Use up lots of resources to take the site offline, then helpfully “offer” the website owner to stop in exchange for payment (extortion)
Captcha is meant to deter the usage of any bot, in that they’re designed to require human interaction in order to pass the test.
Bots can be employed for many purposes, such as mass purchasing of products, en-masse account creation, post creation/spamming, or repeatedly accessing a web page as part of a DDOS attack. A captcha doesn’t necessarily prevent these activities from happening, it’s just meant to make them more difficult by requiring human assistance to complete, which largely defeats the purpose of the bot in the first place.
Lifeprotip – captchas are also looking at your efficiency in completing tasks, hence the follow up choose each picture with traffic lights. On a mobile phone for example you can generally just click the box and the captcha doesn’t see how you got there (bot like) on a computer you have to drag your mouse (human like)
Next ti.e you get a captcha on your phone drag your finger to the box or use your finger to circle the box once or twice showing the system how you got there. You will bypass the picture verification 99%of the time with this method.
Might not answer the question but I do believe it to be worthwhile info everyone should know… unless you are using our responses to create your own bot 🤣
