A perfect illustration of what's wrong with this mode of every poster having the same name of "Guest". No way to know who to ignore as the o.p. suggested.

As people subscribe to this forum, they could be assigned a number as their screen name, so we can differentiate between posters. Everyone having the same name makes it wide open for trolls to talk with themselves and bolster their own opinion endless times, as the kook on Topix does.
