I took a survey on facebook and started received stupid texts on my cell phone. A few weeks later, I saw my Verizon bill was higher than it usually is, and I haven't changed my usage. Come to find that I had "purchased" some kind of monthly service with solow.com. Never heard of them but they were charging me $9.99 a month. I also discovered another bogus "purchase" on my Verizon bill for sendmemobile.com. I didn't authorize that either. Make sure you check your cell phone bill very carefully.
