People who lowball and use smiley Faces.
I have no trouble if you offer, even if it may be god-awful and horrendous, but when you add crap like "add me if interested ;)" or "ill do 2 buds :)"
Add me if interested? You offered 3-4 buds in Unusuals on my 12-13 bud Hat. Why on earth would I ever be interested?
Do you think that it will convince people to take your Lowball or crappy offer? Not for me. If someone offers and uses a Smiley face, I just decline right away with no reason at all.
I find it happens a lot with Russians and sometimes profit-hungry Traders.
I honestly don't get it. It;s pointless and annoys me.
