It's as tedious to update as a bad-word filter, and would only be updated as often as people find new ways to say WTT or LF, which would be extremely close to never.
When it's a constant issue that is what happens, yes, but it isn't a huge constant issue. It's a quality-of-life thing that just keeps things cleaner. Would you rather be muted for accidentally posting a trade once, or would you rather have your trade automatically posted to the Trade chatroom?
Xavier, there are some people who just plainly ignore me when I correct them and keep reposting in Channel. There are no mods, staff, etc around and no matter how many other people tell them to piss off they keep posting anyway.
Look, I know it's not something that happens very often but it's just a bit of housekeeping to prevent mess from occurring in the first place. Is that so bad?
