Here's a simple fix.
NEVER ship the same day to someone you DON'T know.
Period.
In a trade, the person offering to trade ships first, then the one who had the desired animals, the reason for the trade, ships their's. This is reptile shipping etiquette. Don't offer a trade to people you don't trust, don't ship same day to people you don't know, always use the BOI.
Simple.
