Well well well Yahoo! finally decide to fight with spam bots again.They were patched this 2-3 years ago silently and all of sudden they were cut of all spam bots for more than a year.
But after they arrive back in our Yahoo! Pool lounges this time it’s really boring for leagues cause they all have to play in same room and if they ignore 10 bots today 20 arrives tomorrow.
Today when i try to login Yahoo! Pool i saw a new screen which have captcha protection to prevent bot logins.Only bad thing is they don’t allow us to refresh images if we cant read it.The trick is close the window and re try to login so code will change 
Screen says “At Yahoo! we are always striving to provide you with the best gaming experience available. We take SPAM and abuse very seriously and are asking you to verify that you are not using an automated program to access this site. This step helps prevent unfair use and ensures we can provide an environment you and your friends can enjoy.”
Well this only means to me that they finally take care of complaints about this bots and start to do something. I know that spammers already solves captcha protecting at web pages, forums, sign up forms so i thought this will be a permanent solution to keep bots out of rooms ( hope i am wrong).
Foot note : If the captcha code has caps characters like “A1413M” it is okey to type “a1413m”
Funny note: They make code harder to solve for bots but for humans too 
Happy pooling around without Yahoo! Pool bots
