MODERN PROBLEMS: Those annoying robocalls are about to get even worse.

Modern technology has made the annoying practice easy and cheap, and by the middle of the year, robocalls are expected to make up half of all calls that occur in the U.S. Some companies are working on a plan to curtail robocalling, but it hasn’t appeared to help much yet.

According to new data from Transaction Network Services (TNS), which facilitates calls for small and large carriers, April 15 – tax day – will most likely be the worst day of the entire year for robocalls. Call volume was up 13% over last year, so this year may see similar gains.

The analysis, which processed over a billion calls across hundreds of carriers, found that tax season is generally the most dangerous time when it comes to robocalls. Last year, tax day had the most robocall volume, a whopping 143 million “nuisance and high-risk calls,” according to the data.

We cut our landline years ago in no small part due to telemarketers. The spam problem has gotten so bad on mobile — 80% of the calls I receive, at a conservative estimate — that I’m tempted to ditch the iPhone for an iPod Touch (hot-spotted in to a cell-enabled iPad) and just go all-in on text messaging.

AT&T would miss my monthly payments a lot less than I’d miss AT&T, and “wireless cutting” is probably what it’s going to take to get the mobile companies serious about combating the endless spam.
