So he won with a campaign run at zero cost by volunteers? Now I understand why they won't allow him to win.

It would set a dangerous precedent that you can run and win a campaign without multi-millionaire sponsorships from lobbies.

So far, I couldn't find any evidence that he received donations directly. All the bank statements and transactions that have been made public show that other people grouped together and did those things to his benefit.

Old people in positions of power, the so called "Supreme Defence Council of Romania", don't really understand how web platforms work. They released an opinion, which weighs a lot tbh, as did others. But I could find actual proof that the candidate spent any money, neither did the authorities, so far. If there's anyone guilty of breaking RO electoral law, it's the volunteers in the link I posted.

This is (in most cases) not a thing in Europe, generally political parties finance themselves and lobbying is illegal.
