With regard to the moderator’s comments, yes, all of what you say is true. At one time I was doing a website for a synagogue, and used to monitor activity. Surely, in your role as a moderator for a site that can spark wickedness from some realms of society, you need to know who is saying what. It wouldn’t surprise me at all if you told me that there were times people posted threats and that you’ve interacted with law enforcement. This is part and parcel of your job.
However, I still hold by my previous statement. Anyone who knows me in real life hears the same opinions as those I spout on this and other websites, Facebook, and in my emails. The things I shop for online are no secret either, or put another way, why would I care if someone knows what I buy? Everything is 100% legal. Now if I were a criminal, then I’d be more concerned…
