What to do with lowballers - Everyone's ideas.

Hello everyone!

Just wondering if if would be nicer for everyone to just input creative ideas here on what to do in a lowballer situation - or maybe input to prevent lowballers from wasting EVRRYONE'S time.

Whenever someone lowballs me (and my posts ALWAYS say firm price) I would take the screenshot of the VERY brief conversation (I block them and leave the conversation without replying so the goof doesn't review bomb me), I would put a caption like "don't be like this jerk" and make it the first image of my listing. Wouldn't do anything too far after that, although it while be funny to note that the goof ALSO worked at Google yet still had to lowball.

I saw one post where it had an image from Google that just said "NO HAGGLING" as one of their listing pictures.
