I hope this audio captcha will not be replaced again, but claiming right now might be pointless because if typing captchas will come back sooner or later it will be 100% much easier to collect claims. It will be a huge disadvantage for the ones who are doing audio captchas these days. Max claim someone can attain is 240 Claims per hour. Compared to like 500-800 claims per hour with Typing Captcha. Since devs started implementing this type of captcha, i wish to not change it again. For it will be more fair with everyone and kick those bots out. I don't really have the problem with Audio Captcha's noise it's really easy ffs, i don't know why are there people saying that they cannot understand a thing.
The captcha has ONLY 4 Characters which is composed of 1234567890, the trick here is to remember it should be only 4 Characters and all of them are numbers. Sometimes the noise is really loud that it will even mask the one last number, but just let that one go and start the next one. You will get used to the noise and understand it clearly onwards as you claim. Don't worry about invalid claims you will get used to it.
Thanks to the DEVS!
