Hi Shannon, At our institution we have employed a great diversity of techniques, including experimentation with Anubus and Cloudflare Turnstile — depending on the nature of the service. But, in general, the approach has been a combination of a) monitoring traffic more effectively and blocking where necessary, b) rate limiting, and c) web application firewalls (WAFs), as above. On WAFs: We have deployed a WAF on only two services, and only out of necessity. And I would say that they have indeed been effective, though they are not a silver bullet and the other techniques mentioned remain necessary. I dislike using WAFs because it is difficult to anticipate honourable bot actors in our domain, and it is highly likely that indiscriminate blocking of 'welcome' bots is frequently occurring, despite the ingenuity of the WAF approach. My understanding is that Cloudflare Turnstile is free to universities (at least in the UK); my institution has a bunch of other Cloudflare products, so I imagine we pay for Turnstile indirectly. Anubus is OS, as you note. So is 'Go Away', though I don't have experience of using it — it might be superior to Anubus. Apologies if you have already checked it out, but COAR have a website dedicated to 'dealing with the bots'. It includes some useful advice, suggested strategies, and suggested solutions, vendors, etc. See: https://dealing-with-bots.coar-repositories.org/ Hope some of this helps!

[Some people who received this message don't often get email from shannon.lucky@usask.ca. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] Hi all, I am curious what methods folks are using to deal with aggressive AI harvesting on websites - particularly digital project sites. Many of our servers are being hammered with traffic that impacts our service delivery and the methods we have been using cannot keep up. Specifically I am wondering who is using services like Cloudflare or implementing OS solutions like Anubis, or are you using something else? I'm gathering information about what services or methods are being using at academic libraries hosting DH/digital projects so we can look at investing in some kind of service or process solution. What are you using? Are you happy with it? What kinds of costs are associated?)
