This is not a site that is trying to trick you out of your money (which is what a scam is). This is a site that had bad foresight as to how users would use the system, and a front page that isn't blindingly obvious that withdrawal transaction fees are passed on.
On top of being established with a fee system in place that is different value than when the site started, on top of how much a Bitcoin was 'worth', which of course changing by the minute... oh yeah.. also, scams usually try and sell you something. They offer a service for a fee, in the end the service itself is provided.
I can see how the site and business isn't being run up to date and current, but they sure don't have to, and at this point with how people are attacking the site, I don't think half the users complaining deserve any explanation on anything with how little they seem to want to view things from BitcoinPlus' side.
