The red text is uncomfortable to read. So much so that even if you made good points, I didn't read your posts.
Just go with white, and if you need to emphasize something, do it with writing style.
On topic, I agree with the OP. Weirdly enough, I get unsolicited trades all the time in this game. On an unprecedented scale, I might add. Fourteen, fifteen years in WoW and I can probably count the unsolicited trades I got on one hand. One year in FFXIV and I've had, I dunno, ten or twelve?
These folks that do it strike me as odd, too. When I close the trade window they always give some RP-ish response, like, "You've made your intentions known, Sir. I bid you farewell." And then if I message them asking what was up, I never get a response. The items in the trade window are generally a single piece of crafting material - I don't really get why some random person would want to trade me a single animal hide. It's just a bit strange.
TBH I'm just gonna start taking the items and remaining mute. See how that goes, LOL.
