yahoo login error 1236

[Dario Laverde]

I'm getting the following login error from login.yahoo.com with pidgin
2.6.5 and was wondering if anyone else has gotten this:

yahoo, Authentication error: Account locked: Unknown reason.  Logging
into the Yahoo! website may fix this.. Code 1236

Anyone know what code 1236 means?

It's also happening only one some ips - does anyone know if yahoo
throttles or blacklists ips or ip ranges?

thanks,
Dario
