Ignore lists / Actual moderation

Are there ignore lists on the Verge?

Coming from the Microsoft forum there are multitudes of trolls that come in trying to stir things up. I'm sure the same can be said for the Apple and Google forums. Why is there no mechanism to ignore them? Also, why do the mods not bother to moderate? (another topic, I'm sure)

It’s one thing to have substantive criticism, but another to just mindlessly troll. The trolling has made me significantly less inclined to visit this site, and without an "ignore" mechanism I fear that trend will continue, at least for me, but undoubtedly for others who just want to get information on things they are interested in
