American Chemical Society bans university after "spider-trap" is clicked
It's worth noting that many journals don't control the platform their scholarly content. It looks like ACS uses this [Atypon](http://www.atypon.com). That's the likely source of this spider trap, not ACS.Atypon has [a relatively small client list](http://www.atypon.com/our-clients/featured-clients.php). Compare it to [Highwire](http://highwire.stanford.edu/lists/allsites.dtl). I'd be willing to bet that all journals hosted with Atypon share this spider trap—even journals that are supposed to be open access where spidering should be OK.Scientific publishing is weird.
