Normally I'd be quippy about the plural of anecdote not being "data", but this isn't even plural. This is a single anecdote. The claim you have made is "I have encountered fraud, personally, so the system is a disaster."

Well run systems experience fraud. It's something you generally want to minimize, but like, it's not necessarily an indicator that the system is broken. Like... AWS has tons of fraud. AWS is still very much not a disaster. (Well, it kind of is a disaster, but mostly because it's a machine that chews up humans via oncall, which is unrelated to their fraud.)
