Angela Rathmel has published "No, Fair! Evolving Perspectives on Excessive Use in Research" in ACRLog.
Here's an excerpt:
Publishers take an even heavier hand when responding to excessive use breaches. Blocking the user's IP access, or sometimes an entire campus IP range, presumes malicious intent (which it almost never is). This response also exaggerates the stakes involved and misunderstands what is necessary to perform digital research. Strict reinterpretation of print use restrictions in the online environment denies advances in research technology, from basic citation management software to APIs used for text and data mining. It also ignores the very structure of the linked-data world we live in.
