[seqfan] Re: Email addresses Was: offset of A000254 wrong?

[Raff, Paul]

If we're forward-looking and thinking about the upcoming wiki, what about
having email addresses inside a reCAPTCHA, for those that are concerned
about them getting scraped?

You can look on my website for an example, in case you don't know what a
reCAPTCHA is:

It would be more burdensome for the person trying to find the email address,
I agree, but not so much as to prevent the user from abandoning his/her
effort to get it.
