In the mining boom of 1905 and 1906, the Curb market on Broad Street attracted some negative publicity for the "wholesale use of the Curb for swindling". As of 1907, the curb brokers intentionally avoided organizing. The curb brokers had been kicked out of the Mills Building front by 1907, and had moved to the pavement outside the Blair Building where cabbies lined up. There they were given a "little domain of asphalt" fenced off by the police on Broad Street between Exchange Place and Beaver Street, after Police Commissioner McAddo took office. As of 1907, the curb market operated starting at 10'clock in the morning, each day except Sundays, until a gong at 3 o'clock. Orders for the purchase and sale of securities were shouted down from the windows of nearby brokerages, with the execution of the sale then shouted back up to the brokerage. The noise caused by the curb market led to a number of attempts to shut it down. In August 1907, for example, a Wall Street lawyer sent an open letter to the newspapers and the police commissioner, begging for the New York Curb Market on Broad Street to be immediately abolished as a public nuisance. He argued the curb exchange served "no legitimate or beneficial purpose" and was a "gambling institution, pure and simple". He further cited laws relating to street use, arguing blocking the thoroughfare was illegal. The "New York Times," reporting on the open letter, wrote that brokers informed of the letter "were not inclined to worry". The article described "their present ground on the broad asphalt in front of 40 Broad Street, south of the Exchange Place, is the first haven of which they have had anything like indisputed possession."
