Love the irony on that! Which makes me wonder how much valuable content and research in locked away on technologically ancient servers in Cambridge and Oxford.

More modern and up to date than you'd think :) Some departments here in Oxford have a server life-cycle of 3-5 years. It's just that nobody bothers for higher than expected volume of traffic unfortunately (a practice that can be extrapolated to many things in academia).

Wow! Thanks. But, I do not understand the <script> tag in homepage contains lots of ![]+[].

I think it's just a way to document.write his email address, so no bot/crawler can directly see it.

Edit: It evaluate to `document.write('HIS_EMAIL at gmail')`

If the browser can do it what's stoping a headless browser bot from evaluating it all the same? Is it just to lower the attack surface?

>If the browser can do it what's stoping a headless browser bot from evaluating it all the same?

The vast majority of crawlers aren't that smart, headless browsers used to be painfully slow so no one used them.

Evaluating all javascript to see if it eventually writes an email address is not a good idea.

In fact doing so probably violates the halting problem somehow.
