I agree with this post. The trade filter is redundant tbh, it filters out things not even remotely related to trade while those who wanna sell on other chats easily get around it. If someone tries vending on channel or global chat, odds are, someone will tell them to type "/trade" and if they don't listen and keep spamming, report them. The community doesn't like spammers and will get rid of them, doing a better job than a filter that filters out everything but a trade. Pretty annoying if you ask me, especially when it's a long message and you have no idea what triggered the filter cause there's nothing there about trade or involving the letters S E and L in a row.
Also, it never stops people from spamming global/local [EN] with "VENDE/VENDA [Pokemon]" 20 times in a row before someone responds to the support request. I think the trade filter is redundant as heck
