Dude's relax. I've made many purchases from Renderosity and had no trouble. I'm a "white hat", a former hacker who goes after other hackers. (Note to black hats: this email is from a one-off anonymous account, posted through a reflection server I set up someone's PC.) I'm not going to give "how to steal from Renderosity" tips. I can tell you it's likely that the person complaining is running probably Windows without all the current patches, a proper firewall, and unwittingly running spyware on their PC. As mentioned by another, XP service pack 2 will help prevent most spyware. There are numerous commericial available spyware preventation software sold in any computer store. Anti-virus software alone is not enough. I've seen estimates that 1 in 3 PC's have some form of spyware running on it. I think this estimate's a bit high, and it depends on what you call spyware; e.g. tracking cookies. So before you vent on the web masters, take a look in the mirror. If you use Microsoft, patch, patch like the wind!
