Skype may have seen a recent surge in activity but that doesn’t mean that all of those people who are using the VoIP system are pleased with their experiences. The main problem seems to be with VoIP spam (alternatively called SPIT or SPIM) which consists of instant messages sent to Skype users from fake accounts (such as those sexy girls that so obviously want to talk to you). In other words, Skype users still basically have to block each spam IM themselves. Don’t block someone claiming to be Oprah on Skype though because she’s turned out to be a strong supporter of the technology.
