Only two things on the MB that kill braincells for me....

1 - Undercutting by asinine amounts. Example: An item that has been going for 100k+ for months, some chucklehead posts several for 10k.

2 - People posting items for below VENDOR sell price. That item that you can sell to the vendor for 49 gil, posted on the MB for 30 gil... WHYYYY?! Vendor that thing, bruh!

Y U HAET MUNNIES?!
