For the most part, I see people edit their post (if it's still editable) with the
emoji when they have fulfilled their trade needs. Other times they may add a new reply to the post, even though it's now irrelevant.
My suggestion is that we offer a user operated "close topic" option so that once the trade is completed, they can just close the topic instead of editing or even worse putting it back to the top of the list when it's no longer valid.
I think there would need to be some controls on the use of this option. I'm not sure how many trolls exist here, but I know they lurk... I'm torn between a post count or timer for the "close topic" (or maybe a combination of the two) option to become available for the original poster..
In conclusion, I hope this is actually considered because I think it would lower unnecessary post count.
Thanks for even reading this!
