Trollcakes: sleuthing bakers will hunt down your trolls, inscribe their hate in icing, and deliver edible words

I’m skeptical here - seems like this would only work if the troll proudly displayed their real identity, which often isn’t going to be the case. If they really had the ability to consistently figure out where troll/hate messages are coming from, that would be the more valuable service. People could track down those making rape/death threats (and instead of giving them a nice frosted brownie, nail-gun the offender’s hands to their keyboard).
