Thought this article was interesting - I got it from my weekly subscription of Deaf Weekly. Makes me wonder what the 85 to 90% of scams were about and who they contact.
"The IP Relay system may help criminals more than the deaf community, reported MSNBC last week. About 22 million calls are placed through IP Relay each year at a cost of $92.5 million, but one former operator, Cathy Audia, said about 85 to 90 percent of calls she handled were scams. "Very rarely did we get an actually hearing-impaired call," she said. Another former operator, Sheila Satterwhite, said, "I felt like a criminal every day I left work." A memo obtained by NBC showed an IP Relay director warning operators not to discuss the issue publicly. "Please do not risk your jobs and your own integrity," wrote the director."
