[Batman] This Matches Malone guy... why do people trust him?

Every small-time legitimate businessman in Gotham City seems to have heard of Matches Malone, and most of them seem to be of the opinion that he's a stand-up guy. But where do they get that from? What line of business is Malone in? What gangs is he associated with? What jobs has he done?

Why should I, a hard-working businessman, trust Malone with the hypothetical details of my alleged and unproven felonious activities, the sort of information which I obviously would not share with just any potential snitch?

Matches was a an independent crook that had a well known reputation. He was dependable and got the job done and by criminal standards he was pretty ethical. He ended up dying and Batman decided to hide his death and use the Matches persona to his advantage. He maintains that reputation so that he can use it for undercover work.
