A former PayPal Inc. executive kicked off a Twitter rant against the company last May with a picture of himself giving the camera the middle finger.

A few hours later, Rakesh “Rocky” Agrawal reportedly called PayPal’s global brand and communications officer a “piece of shit” and a “useless middle manager.” Some of the tweets, sent after 1 a.m. from Jazz Fest in New Orleans, were so full of typos that they were incoherent.
