Most of em, not all of em, but it is sort of an initial redflag. I’ve also the 3 or 4 I’ve ever managed to get off Trade weren’t very contributive or productive, in any capacity, just sat there not talking in G chat, but look over in Trade and they’re running their mouths 0-90 with mad trash talk. Latest person I asked when they said LF guild and asked what kind: “One with a hearthstone.”
You might find some gold nuggets, but I wouldn’t say it’s a good route in general for recruitment.
