Blacklisting not (always?) working
At least on the URLs I was brave enough to open, Wirefish did not mark them as blacklisted, or display them in any other way than anything else. This is possibly because the URL that I visited is not the same one that Wirefish sees. For example, I visited http://2ni2.com/tops.htm in my browser, but Wirefish displays an entry for “2ni2.com.”, not “2ni2.com/tops.htm”. Another possible cause that we found was that when we ran SELECT count(*) FROM blacklist in sqlite, we got 0. Not sure why that is.
Our recommendation is to sidestep this issue and block by domains, or at least do so in addition to by URL. This makes sense because there are many sites, take Pornhub for example, for which any link should be blacklisted. But Pornhub has millions of links and adds new links frequently, so it is intractable to blacklist every possible individual URL at Pornhub.
