+- Advise IWMI colleagues on best practices for thumbnails
+- Add a handful of mappings for incorrect countries, regions, and licenses on AReS and start a new harvest
+  - I sent a message to Jacquie from WorldFish to ask if I can help her clean up the incorrect countries and regions in their repository, for example:
+  - WorldFish countries: Aegean, Euboea, Caribbean Sea, Caspian Sea, Chilwa Lake, Imo River, Indian Ocean, Indo-pacific
+  - WorldFish regions: Black Sea, Arabian Sea, Caribbean Sea, California Gulf, Mediterranean Sea, North Sea, Red Sea
+- Looking at the July Solr statistics to find the top IP and user agents, looking for anything strange
+  - 35.174.144.154 made 11,000 requests last month with the following user agent:
+
+```console
+Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36
+```
+
+- That IP is on Amazon, and from looking at the DSpace logs I don't see them logging in at all, only scraping... so I will purge hits from that IP
+- I see 93.158.90.30 is some Swedish IP that also has a normal-looking user agent, but never logs in and requests thousands of XMLUI pages, I will purge their hits too
+  - Same deal with 130.255.162.173, which is also in Sweden and makes requests every five seconds or so
+  - Same deal with 93.158.90.91, also in Sweden
+- 3.225.28.105 uses a normal-looking user agent but makes thousands of request to the REST API a few seconds apart
+- 61.143.40.50 is in China and uses this hilarious user agent:
+
+```console
+Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.{random.randint(0, 9999)} Safari/537.{random.randint(0, 99)}"
+```
+
+- 47.252.80.214 is owned by Alibaba in the US and has the same user agent
+- 159.138.131.15 is in Hong Kong and also seems to be a bot because I never see it log in and it downloads 4,300 PDFs over the course of a few hours
+- 95.87.154.12 seems to be a new bot with the following user agent:
+
+```console
+Mozilla/5.0 (compatible; MaCoCu; +https://www.clarin.si/info/macocu-massive-collection-and-curation-of-monolingual-and-bilingual-data/
+```
+
+- They have a legitimate EU-funded project to enrich data for under-resourced languages in the EU
+  - I will purge the hits and add them to our list of bot overrides in the mean time before I submit it to COUNTER-Robots
+- I see a new bot using this user agent:
+
+```console
+nettle (+https://www.nettle.sk)
+```
+
+- 129.0.211.251 is in Cameroon and uses a normal-looking user agent, but seems to be a bot of some sort, as it downloaded 900 PDFs over a short period.
+- 217.182.21.193 is on OVH in France and uses a Linux user agent, but never logs in and makes several requests per minute, over 1,000 in a day
+- 103.135.104.139 is in Hong Kong and also seems to be making real requests, but makes way too many to be a human
+- There are probably more but that's most of them over 1,000 hits last month, so I will purge them:
+
+```console
+$ ./ilri/check-spider-ip-hits.sh -f /tmp/ips.txt -p
+Purging 10796 hits from 35.174.144.154 in statistics
+Purging 9993 hits from 93.158.90.30 in statistics
+Purging 6092 hits from 130.255.162.173 in statistics
+Purging 24863 hits from 3.225.28.105 in statistics
+Purging 2988 hits from 93.158.90.91 in statistics
+Purging 2497 hits from 61.143.40.50 in statistics
+Purging 13866 hits from 159.138.131.15 in statistics
+Purging 2721 hits from 95.87.154.12 in statistics
+Purging 2786 hits from 47.252.80.214 in statistics
+Purging 1485 hits from 129.0.211.251 in statistics
+Purging 8952 hits from 217.182.21.193 in statistics
+Purging 3446 hits from 103.135.104.139 in statistics
+
+Total number of bot hits purged: 90485
+```
+
+- Then I purged a few thousand more by user agent:
+
+```console
+$ ./ilri/check-spider-hits.sh -f dspace/config/spiders/agents/ilri 
+Found 2707 hits from MaCoCu in statistics
+Found 1785 hits from nettle in statistics
+
+Total number of hits from bots: 4492
+```
+
+- I found some CGSpace metadata in the wrong fields
+  - Seven metadata in dc.subject (57) should be in dcterms.subject (187)
+  - Twelve metadata in cg.title.journal (202) should be in cg.journal (251)
+  - Three dc.identifier.isbn (20) should be in cg.isbn (252)
+  - Three dc.identifier.issn (21) should be in cg.issn (253)
+  - I re-ran the `migrate-fields.sh` script on CGSpace
+- I exported the entire CGSpace repository as a CSV to do some work on ISSNs and ISBNs:
+
+```console
+$ csvcut -c 'id,cg.issn,cg.issn[],cg.issn[en],cg.issn[en_US],cg.isbn,cg.isbn[],cg.isbn[en_US]' /tmp/2021-08-08-cgspace.csv > /tmp/2021-08-08-issn-isbn.csv
+```
+
+- Then in OpenRefine I merged all null, blank, and en fields into the `en_US` one for each, removed all spaces, fixed invalid multi-value separators, removed everything other than ISSN/ISBNs themselves
+  - In total it was a few thousand metadata entries or so so I had to split the CSV with `xsv split` in order to process it
+  - I was reminded again how DSpace 6 is very fucking slow when it comes to any database-related operations, as it takes over an hour to process 200 metadata changes...
