I don't disagree with it being run by sleazy people with sleazy business practices. From everything I've read, I'd concur with this statement.
An epidemic of cheating over the internet is no more a concern than the "epidemic" of cheating. The internet was just a means to an end... just like party lines, dating services, the bar, the office and everywhere else people of our species comingle without their partners. Cheating is no more an epidemic now than it ever was. People just changed media. Perhaps if it's truly the epidemic you suggest, then instead of that being a concern to people who intend to get married, we as a species need to re-evaluate if monogamy is actually human nature or if it's just wishful thinking impressed upon us by the dogma of our upbringing.
