There needs to be an automatic redirect for trade related chat when it gets posted in any channel besides the trade channel for WTS WTB and WTT... the All channel gets spammed with WTS and WTB posts quite often, to everyone's annoyance. Every time it happens someone tells these people to go to the trade channel, both by normal users and mods alike. With this, that annoyance should be reduced a LOT, save for people actually trying to circumvent it.

Just tell them to use /t at the start of their copy pasta, most people do it by mistake, using /t means you cant make a mistake and most people are happy to use it once you inform them.
