My question in these events is, so why not investigate it and block the running BEFORE the vote? People only care about illegal hiding of funds post elections? Why even let it go on if you can get evidence so quickly just after? In these 6 days what came out that wasn't out say, 10 or 20 days before voting day?

Because before the first round he was considered a nobody, and the second round was scheduled to happen two weeks after the first round. It's too short of a time.

2 weeks is more time than the 6 days since the election. They could've decided to stop things then. I get what you mean agree it's probably messy with the timings, but one gets the feeling that if you lose you can do all the election fraud you want, which is kind of suss to me because people can use decoy candidates for the fraud and if they lose nobody looks into it.

The law is about what he is spending. If I go and pay for ads on my own initiative, he doesn't need to declare it just like Basescu didn't declare all the stuff NGOs paid for him back in the days.

EDIT: I do find it impossible for him to spend 0 on it though. You have to travel from A to B (at the very least)
