The particular case that made the blacklist famous in at least some
fora, and exposed quite a bit on how it worked:

https://en.wikipedia.org/wiki/Internet_Watch_Foundation_and_Wikipedia

"the action also had some indirect effects on Wikipedia, namely
temporarily preventing all editors using said ISPs in the UK from
contributing to any page of the encyclopaedia, and preventing anonymous
edits from these ISPs while the URL remained on the blacklist. This was
described by the IWF as unintended "collateral damage".[7] This was due
to the proxies used to access Wikipedia, as Wikipedia implements a
blocking policy whereby contributors can be blocked if they vandalise
the encyclopaedia. Therefore, all vandalism coming from one ISP would be
directed through one proxy—hence one IP—and all of the ISP's customers
using that proxy would be barred from editing."
