That is illegal in Romania, all campaign contributions must be declared, even if you're not a willing beneficiary.

To be honest, I couldn't find any proof that the candidate got funded by anyone, and all news articles express opinions of old people in positions of power who don't understand how web platforms work.

If I suddenly decided to print campaign posters myself and gather a group of people to donate to me for doing so, in favour of some random candidate, shouldn't the constitutional court cancel the elections again?... Bad precedent.
