Like I said before the VAT number you gave belong to another company, with a different address in Tel Aviv , not Givatiam, and a different contact address for mails.
Anyway, you should be worried, what if someone decide to report you using this link
Israel Tax Authority clicking on
Department Hotline on the left side..

All they have to do is give the VAT number you posted with a link to your site , your contact info, some links to your posts, specially the one where u gave that VAT number or bragged about how much money and costumers you have.
On top of that , The Israeli Gov pays who ever reports, between 10% - 20% commission of the total sum of money won in lawsuit. A quicker way to make money, quicker than what you promise in your "legit" site...
