I don't know if that's the case. Rewards have been dropping due to Bitcoin's increase and I recently deposited 80,000 from coinpot. I had no captcha before depositing that (and right afterwards too), so I don't think I've caught up in just a few days.
Check in your personal stats page and you will see the total and then compare to your balance.
Also, if it is set by Google as you say, why is it so much easier for freedogecoin and the moon sites? I'm having one screen on those sites and even if I don't do it 100% correctly I pass, but I still can't pass the one on freebitco.in. I'm not doubting you, just wondering.
From personal experience, I use several websites that use reCapcha and when I do a lot in short space of time they all get harder. What you say doesn't match what happens to me, I can't think of why that would happen to you.
As far as i can see, there are different stories for each user. I had some problems in the past, and it was so bad in fact i had to format my computer in order to fix it( i work with faucets daily, and it was a "must" for me).
I believe there is a much more complicated algorithm behind this service from google. It might be measuring some other actions and circumstances in order to adjust difficulty level for each user.
This is interesting. This might be the reason why reCaptcha is easier for me and not for everyone else. But the other user is saying that reCaptcha at the Moons are easier for them compared to FreeBitco.in which is not so for me. The difficulty level is basically the same including at FreeDoge.co.in. Sometimes the images are the same and if I miss a click [a square] here and get it right/wrong it will be the same everywhere. But I do hate the 'click all cars or roads and verify when there are none' - I simply skip when I see those.
I know I'm alone in this, but I like reCaptcha, it's easier because it's in images, you simply click or touch the square like a game and it's done quickly, compared to the Black-Text captcha and Solve Media where I have to type the letters which is especially difficult when I'm using my phone. But after a while I'm able to adjust even to the Black-Text captcha which was a bit harder to see especially the 'i' and the 'l'.
Exactly. I think the site owners will be a bit more concerned at which one is best at stopping the bots than we are. So his criteria for choosing is based on something that we are not fully aware. I would hazard a guess that also has something to do with why it switches from one type to another every so often as that may catch a few bots out.
I suggested that wetsuit should change the captchas every now and then much much earlier in the thread, but I don't know whether he has made that decision long before that. It should concerns us too because if the bots are hurting the business they are hurting all honest users, so we all lose if they win.
