I'm not trying to imply that calling a GM is a better option. I've been trade-griefed, I handled it. I do have at least one friend who cannot handle it though. They are one of those people who will never say anything during a dungeon run because of their social anxiety. They've locked themselves in the inn room just because somebody was following them. I do not think they would be able to handle trade-griefing and contacting the GM might seem the only way to deal with it to them. I didn't know that blacklisting or setting your status to busy would block trades, I'll let her know.
