The easiest way I see to resolving this issue it to make 1 or 2 districts in the main towns, such as Ascalon and LA as Trading Districts only.
This could have several benefits to the rest of the gaming community and overall performance of the game.
It would save all those people trying to look for a group from having to troll through the Spam to find someone who wants to group, and those that are looking for something to buy or sell know where they need to go.
This would lower the amount of trade spam in the other towns which would reduce overall lag, as they would now have just 1 or 2 districts they can trade in, so wouldn't have to spam the channels as often to get noticed and try and outspam everyone else.
This way, they could have 4 trade channels of different colours so all there items would get noticed more easily.
It would save the frustration on people who get annoyed by this(I do, but I move town), and they don't have to tell people to use the Trade Channel anymore, which in itself would greatly reduce the lag.
Having just a few Trade Districts would also help A-Net and GW Support track unscrupulous individuals who are cheating, scamming whatever you will and make it easier for them to become banned, as they would have less logs to look through, again reducing the amount of lag.
And the bonus for Traders is they can get on with what they want to do, and trade without them having to worry about all those that keep telling them what to do, which reduces lag yet again, as they no longer have to reply with F&*K Y8u, and P67s O#f etc etc.
If anyone is caught abusing this system outside the Trade Districts, they get a warning. If they are caught again, they get a 1 week ban, and if they are caught for a 3rd time, they are banned for good.
You could then remove the Trade Channel from all the other districts and hopefully this would also help improve the performance as there is one less channel to monitor in all the districts.
This, in the end would save having to worry about a reporting feature being abused by individuals, and would probably be a lot easier to maintain and implement.
Anyway, just my thoughts after reading what has been posted here.
