Frankly, even 222 from tax pros isn't nearly the issue that breaches from places like LinkedIn and many, many, many other sources are responsible for (including banks, retailers, and financial institutions).

Rather than getting all hot under the collar, I'd recommend that we all review our data security protocols, and make sure our cyberinsurance is up to date!
