PrivacyStar mobile app users have filed 100,000 complaints with FTC over telemarketers

PrivacyStar is a smart phone app that works on Android and BlackBerry phone. The app's main purpose is to block unwanted calls and text messages, and to provide Caller ID for unknown callers. But the app has an arguably more interesting feature: When you get one of those annoying junk robo-calls from telemarketers, you can use PrivacyStar to immediately file a federal complaint against the incoming number. PrivacyStar says its 600,000 registered users have taken a shine to the feature, filing 100,000 such complaints with the Federal Trade Commission. The company says the FTC liked the app so much that the agency asked PrivacyStar to add a feature that would allow users to complain about debt collectors violating the Fair Debt Collection act -- for instance, trying to gain information about debtors by pretending to be someone else.
