I mean, there’s obviously something going on. Public sentiment towards Ukraine is still strong and you still see yellow and blue flags flying but sympathy for Israel was never as strong and it’s since massively died off given how they’ve reacted. The vote is clearly not a reflection of genuine public opinion. But what’s going on, are certain people just voting loads of times?
You can vote 20 times from any one phone number, and they don’t check if two numbers (or 200) are owned by the same person. And SIM cards aren’t that expensive. Goosing a Eurovision contestant’s vote would be relatively cheap and involve no breaking of any actual rules, let alone laws.
Maybe when the European Digital ID scheme comes in, they can use this to restrict votes per person, though this would still leave countries like the UK, Switzerland, Armenia/Georgia/Azerbaijan and Australia open to manipulation, unless they locked down their voting similarly. And you want something like Eurovision to be relatively frictionless, as it’s meant to be a party rather than a serious exercise in democratic governance.
