I've never had that problem on Yahoo. In fact, my current Yahoo password has special characters in it. I don't use Yahoo as an ISP, though, so maybe it's a different restriction.
Yeah, I'm pretty sure it's an ISP thing. I've had my yahoo account before using them as ISP, and I used special characters in my password. I suspect the people responsible for the ISP version of Yahoo are not the same people responsble for the non-ISP version. Either that or their integration is just not all that great.
It is unbelievable if they prohibit special characters in passwords to help protect from SQL injection, as it is not a new problem. There are various methods to sanitize user input... But then, they just had a merger. Perhaps they no longer have the same people managing their site.
