- Ah, we've apparently seen this server exactly a year ago in 2017-11, making 40,000 requests in one day...

- I wonder if it's worth adding them to the list of bots in the nginx config?

- It's making lots of requests and using quite a number of Tomcat sessions:

- I could add this IP to the list of bot IPs in nginx, but it seems like a futile effort when some new IP could come along and do the same thing
|

- Perhaps I should think about adding rate limits to dynamic pages like `/discover` and `/browse`
|
||||
- I think it's reasonable for a human to click one of those links five or ten times a minute...
|
||||
- To contrast, `78.46.89.18` made about 300 requests per minute for a few hours today:

- Also, this is the third (?) time a mysterious IP in Hetzner has done this... who is this?
