<p class="MsoNormal"><span style="color:black">The professor was using the direct URL rather than the WAM proxy when the block was triggered. I checked our WAM logs and it looks like after the IP was blocked, that he went through the WAM proxy. This didn’t
trigger a block on our hosted server IP (thankfully). Maybe the proxy gives enough of a delay that it doesn’t trigger blocks?<o:p></o:p></span></p>

information concerning their excessive download threshold for blocking an IP address, we were told that the “downloading rates that trigger blocks are too rapid for any human to achieve.” I hope this helps.<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hello everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We’ve had two instances in the past week of users triggering ACS’ excessive download IP block via EndNote’s “Find Full-Text” functionality.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are you aware of a certain number of downloads that triggers the block with ACS? For example, one of our users employs this feature in EndNote on a regular basis, usually downloading a few articles at a time (not a problem). The IP block
occurred when they had a problem with their EndNote account and lost all previously downloaded articles, and then attempted to replace the missing articles all at once. So I know the problem lies somewhere between downloading a handful of articles and hundreds…
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is ACS the only publisher that is sensitive to this? We do on occasion have IP blocks from other publishers, but these two incidents are the first time they’ve been connected to EndNote (that I’m aware of).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How are your institutions handling this? I’m not sure yet how to advise our users on “Find Full-Text” in EndNote. I don’t want to unnecessarily scare them from using functionality that is useful, but of course want to protect ourselves
and educate as much as possible. I did some googling and some institutions advise against even using the functionality and others caution against using it for “too many articles at once”, and include a warning against “excessive downloads”. What are you
saying to users and where are you posting/saying it?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
