Since the trolls are back in full force, here's my updated ignore list with instructions on how to add it to your own (kindly provided by macgsa)!

Go to
ProfileThen
Ignore user optionsCopy and paste the above names into that magic box.
Presto!
No more trolls!

That's one heck of a list! I thought it was going to be like 50 usernames, not 500 LOL
