Runescape Trade Scams
Trade scams in runescape are likely the most frequent method people use to cheat. Jagex have so far not been able to effectively prevent this type of scamming on runescape due to the nature of the way their ingame report abuse feature works.
I made sample video to try and highlight the fact - simply as when I went to world 18 Edgeville bank a scammer by the name of 69Stoner4 tried to scam me by switching the total amount of cash in a trade. I was aware and took my time and checked the 2nd trade screen, many people do not check the 2nd trade screen and fall victim to such scams.
The video serves a purpose to inform people of the importance of being vigilante when dealing in busy trading locations. I didn't capture the scam on video as I was simply starting to record at the time - maybe next video I get the scam in action.
Hopefully Jagex realise the scale of such trade scams in runescape and properly implement a method to report people while the trade window is open. Currently this isn't the case so scammers are easily able to avoid being reported in any busy trading area.
