Possibly scammed in a trade? What can I do?

[Tyrrion]

First off, I'm going to be as vague as I can here as I'm not entirely sure what I can do here, or if I actually was scammed, but I had a trade that rubbed me the wrong way a few days ago and was wondering what I can do about it.

The person in question sent me a tell for a trade of an item from me for plat from them. They eventually met with me, and the item and cash were put up in the trade window. At some point, this person used the Hide skill during or before the trade, and I didn't notice until I tried to buff them after the trade menu closed.

I didn't check my exact plat totals before or after the trade, and the value of the item was small, so I don't have any solid evidence that something wrong happened, but the whole thing rubbed me the wrong way. The value of the item isn't a concern to me, only to see that justice is dealt if there was wrongdoing here.

I vaguely remember something about something like this being an exploit back in the day, and just want to know what my options are. Is this something the GMs can confirm if they checked some logs given the location and time? If this is even a possible exploit, is that allowed here?

Thanks for taking the time to read this.
