Character Borderland from broke to a millionare in a matter of a second

[Severance]

so i was playing Borderlands as a hunter level 4  and was a host in an online game, so was doing these missions and all , till this badass siren joined the room and started throwing really really expensive stuff, and being the noob i am i didn't know what the heck is happening and the people i am playing with are taking everything he is throwing up.

so i in my stupidity ignored them... but after awhile he threw a gun that requires level 824948992094090129049092409024900240249 or something  and since i didn't need it in eternity, i sold it , and when i did i got a trophy for being a millionare (WHAT?!) then i checked my money and it shows my money maxed out =s

while this is all good and dandy , how did the devs let a thing like this slip through? its a major cheat and the fact the guy told me "can you kick me before it saves?" and i didn't know why so i did what he asked for, i'd guess its so he can get his stuff back.

now the game became too easy to play =/ , i might as well restart my character.
