A comical scenario that I consider among possible variants: the Fiverr seller contacted Russian mafia to outsource his work further. Mafia turned it on and their overloaded servers made a powerplant here in Ashkelon to make noise (isn’t it the noise I heard that day?) The seller asked the mafia to turn it off after my messages to him, but mafia cannot turn it off because they overloaded their computer and mafia is dying of hunger spending all money on my project. I don’t say, that it is so, but it looks realistic even without considering help of God.
The DDoS attack seems even to increase my future profits, because it may make Amazon ads to index my site faster.
