So i tried to make an account on G2G using my usual address at @yahoo.de. G2G refused, saying it was not authorized. So i created a new mail adress JUST FOR G2G!

I am mildly pissed off. If driving away customers by blocking certain e-mail adresses is the goal here, then that's a definitive achievement. I am so pissed...

Some of the email domains (like hotmail for example) were blocked because of spam bots coming from said domains. I assume a similar case is for yahoo.de as well.
