Top 10 Internet frauds
Internet auction fraud
Consumers say they've received an item that is less valuable than promised, or don't receive the item at all. FTC advice: Insist on using a credit card or escrow service.
Internet service provider scams
Reports of being trapped into long-term contracts of ISPs with big penalties for cancellation. FTC advice: Read bills carefully for unexpected charges.
Web site design/promotions -- Web cramming
Getting a custom-designed Web site for a 30-trial period could be more than what was bargained for. FTC advice: Review telephone bills and unfamiliar charges.
Internet information and adult services -- credit card cramming
Using a credit card to prove being older than 18 years could prove costly. FTC advice: Always dispute charges that were unauthorized.
Multilevel marketing/pyramid scams
Some multilevel marketing programs are actually illegal pyramid schemes. FTC advice: When products or services are sold only to distributors, there's no way to make money. Avoid plans to recruit in such a scenario.
Business opportunities and work-at-home scam
Promises of earning "big money" while sitting at home are often too good to be true. FTC advice: Talk to other people who have dealt with the company or an attorney.
Investment schemes and get-rich-quick scams
Making an initial investment in a day trading operation claims to offer huge returns. FTC advice: Always check with federal securities and commodities regulators to discover the level of risk.
The lure of a cheap trip with "extras" at a bargain-basement price often doesn't reveal hidden charges and additional requirements. FTC advice: References are necessary, as well as a written cancellation policy.
Telephone/pay-per-call solicitation fraud
"Free" access to adult material and pornography by downloading a "viewer" or "dialer" program is cause for concern. Through the program, consumers reported their modem being disconnected, then reconnected to the Internet through an international long-distance number. FTC advice: Read phone bills carefully and don't download any program to access a "free" service without reading all disclosures.
Health care frauds
Items not sold through traditional suppliers are "proven" to cure serious and even fatal health problems, but in actuality people lose money to these sites. FTC advice: Always consult a health care professional.
