Rant about trading

So, for weeks now ive been trying to trade an unicorn / apple owl, i always put a trade stand in the middle of the server and wait for offers, but lately ive been getting an insane amount of lowballs (like a minute ago i got offered 18 ants for the uni ?) and when i decline ppl chase me around the map saying im rude or that i want an overpay 😭
something thats also happening thats making me abit mad is: i make a trading stand > someone trades me > asks to check my backpack > add an pet im looking for > i accept the trade > they accept the trade > 5 seconds pass > they decline and ask me to add something else?
n dont get me started on ppl who trade you just to check ur backpack .. like .. can we be normal
