bypassing captcha - iamnotactiveanymore - Dec 12, 2016
Hey, i am making a bot that automatically signs me up for kik username sites, and i need to find a way to bypass captcha, do you guys know how?

You can't really bypass captchas with a bot, that's the whole reason for a captcha.
If you wanna bypass it you probably have to manually do it.

Deathbycaptcha and other sites offer capcha solving services.

You can't bypass something specifically designed to stop bots, but you can do it using captcha farms (humans complete the captcha). DeathByCaptcha and 2captcha are services that provide the solution for this.

Some captchas are solved. If they're using some old captcha system, there are programs with over 60% accuracy which is enough.
Renting captcha solving is often a viable option.

you wouldnt be able to bypass captcha at 100% simply as it always changes and updates some softwares like xrumer can do many bypasses

You don't need 100%, 70% is already awesome. Good thing is that you can easily get 1000 solved captchas for 1$ to 'train' your program.
Check out some talks at defcon and blackhat about these algorithms. They are the reason why Google started the image captcha project. Text captchas are not reliable.

Well again there is not a standard way to do that. Over the previous years I have discovered the following interesting situations.
1) There are 5 captas that chainged randomly on page load (which gives tou 20% chance to find the right one on every try)
2) The numbers that te captchas display are generated via a simple algorithm which implies that you can stastically found a formula that predicts the captchas
3) Image to text (Difficult)
4) In site vulnerability (More specifically the captchas exist in a hidden form,cookie,url or somewhere else on the page)
5) Reusable old captchas
