circa, can you post the trade histories of when you stole apt's scattergun, traded it to your alt bluemoon, and up to where you purchased the hat with it? the item histories of the hat and the scattergun are missing some pieces: Sluggy, the guy that you seemingly bought the hat from, would've had the scattergun pop up in his backpack since he's a perma-trader & never made his backpack private... unless you're not being forthright with what you got from his scattergun. you also have a pending steamrep report on your main, but it seems like that happened before the item trades occurred.
regardless, the main issue is that the scattergun is worth about twice as much as that clean hat (probably more if he upped the valuation by emphasizing the signature from Lucky Luke), those extra items add up to below a key, and assuming that those 33+ keys in bluemoon's backpack came from the scattergun trade, there's no way in hell that you nor mukhtar went through that many MvM tickets (<1/2 the price of a key each) considering how little both of you have logged since then (unless you're playing on epic alts????)
if you want to repent, be an adult and give him back the full monetary value of that gun instead of making your retarded friend mukhtar give a half-assed "i'm so sry... i rly want to play games so here's something that's cheaper than what i stole from u and i hope my sentiments make u feel better :)" apology on your behalf.
but since you both are immature sociopaths & it's very unlikely that circa will make proper amends, circa can start by filling in the missing gaps of the trade histories & show us how much he is actually trying to give back to apt. since mukhtar is the one giving circa's stuff back, he should post his trade history too.
apt is too nice, but i'll look out for him.
