“Facebook gives people who would cheat, or who might be on the fence about cheating, more opportunities,” says clinical psychologist Lisa Boesky, aka TV’s Dr. Lisa. One in five of 5,000 American divorce filings studied by the British company Divorce Online listed Facebook behavior as a cause.

Yet it’s still surprising that BrickHouse Security says sales of surveillance tools have spiked nearly 2.5 times in the days leading up to Valentine’s Day. New York City-based BrickHouse provides tools to law enforcers at the NYPD, LA County Sheriffs, and the FBI.

BrickHouse, a company that seems to be a go-to for TV producers — they’ve been on CBS, NBC, ABC, CNN and Fox News — recommends the Stealth iBot monitoring tool. It installs in 5 seconds from a USB drive, says BrickHouse. Then you remove the drive and let the installed software record all activity on all accounts, including Facebook use. Later, you sneak onto the PC and recover the damning evidence. The iBot software will snap up to 10,000 screenshots.

Of course, tech-sector workers like myself have proven over the years that the most elegant solution to the threat of cheating is to not have a girlfriend at all.
