in the follow forum:
https://bitcointalk.org/index.php?action=login
there is the reCAPTCHA also for to do login... and not only for register user.
In order to prevent spam there is a limit to the number of post in a specific times. So that should be enough for security... but administrator decided add reCAPTCHA also to login. It is something strange but it is so...
I see some other thread in this forum asking for that, and I understood administrator do not provide help to resolve that....

Considerate that this reCAPTCHA is for to do login maybe in this case it will decide help...
Say that my first question is very basically:
It look like this reCAPTCHA of the forum I provided is made by google.Is there a true solution to resolve reCAPTCHA? Or maybe it is not possible?
Maybe I am wrong, but 99% of reCAPTCHA on the webs are made by google.
So my second question is the follow:
Please, let me know, an of course if you can provide some good information, it will be very apreciated.If there is a solution for google reCAPTCHA, is this solution universal for all google reCAPTCHA?
Thanks for support
