JTA — Prime Minister Benjamin Netanyahu on Sunday posted what he described as his personal phone number and invited Israelis to contact him with their questions and problems.

It was an election-season stunt that drew such a flood of responses that the number’s WhatsApp account was blocked within minutes and those calling received a busy signal.

It also drew suspicions that it was a ploy to collect voter data.

In a video posted to social media, Netanyahu is seen with longtime adviser Topaz Luk, who asks the prime minister whether he can publish his phone number. Netanyahu initially reacts with disbelief, saying, “Topaz, have you gone crazy?” before agreeing.

“I want to hear from you. Your suggestions, your questions, your problems. I want to hear, so leave me a message,” Netanyahu said. He added that he could not promise to answer everyone but would respond to as many people as possible.
