Excellent point that this is a tool that allows anti-semites to communicate in a less publicly visible manner. The database they are using is gated so the best an actor could hope for is to flood the submissions to make updates more costly. Of course such an action would only strengthen the resolve of these groups. In terms of mining the signal, one could try to look for correlations between people being added to the list and comments made against those people. The idea is that people using this plugin will have their behaviors influenced in a detectable manner. Effectively scrape the comments sections of new sites and fish out those using the tool.
