I am only interested in contact from human beings, not spammers or bots, so I am going to write out my e mail address in words that you will be able to understand, but which won't encourage crap I don't want..... It is: rob at robertpoynton dot com. Of course, at the rate AI proceeds, they might be able to read this anyway, but it seems worth a go. (Twitter is: @robpoynton).
I hope that's clear, even it it does means a little more typing...
By the way, it turns out that simply asking someone to click on a button saying 'I am not a robot' is more effective than a Turing test. Apparently the way we people do that is a real give away and bots can't imitate it. I love that.
