When I try to search Google Scholar, I get an "unusual traffic" or "Invalid domain for site key" error
Answer
Google gets grumpy when too many people search Google Scholar from the same Massey IP address, which they interpret as their servers being spammed.
However, there is another way you can access Google Scholar, and still see Massey full text links on the right.
Follow these instructions:
1. In a private/incognito browser window, go directly to https://scholar.google.com
2. Click the 'hamburger' (3 horizontal lines) icon at the top left, and select Settings.
3. Click on Library links in the left sidebar menu.
4. In the search box, type massey (or similar) and click the search button.
5. Tick the relevant boxes that appear, and click Save.
