I have just had yahoo refuse to send my daily digest: something which I have been doing ever since yahell groups disintegrated. Your robot thinks that it is spam. That is the same as the useless farcecbook. USA programmers cannot write software capable of detecting spam. That is why I won't buy a robotic car. I did send it from my other account, with a copy to yahell, which refused to receive it. All I see is weasel words 'improve further': it has gone steadily downhill under the new owners.
