Shouldn't a safety then be worth aroung 17 points? Or do you really get to see more safeties than TDs?

Yes, because in Mexico's Electoral Procedures Code it is clearly and strictly forbidden to produce a video that attacks another political entity.
The reason behind this is that it is implied that the money for the production of this video came from Federal resources and incentives to said party.
It is also forbidden to advertise a certain social programme -say, hot lunches for school children- and use it for personal gain -"brought to you by Party A"- in the understanding that the money for the programme came from federal funds, thus supporters of Party B would not be happy that their tax money is used for the gain of the other party.
Personally, I think it's a very good idea.
In the case of the Youtube video, the party that wants to air the video says that since they're not really paying for the transmission of the ad it's fair game under 'free speech'. IFE (the electoral institution) says that it's not the transmission, but the production of the video that used public funds, and that expressly attacking an adversary, be it a person or a party, is forbidden anyway.
With 'the cat out of the hat' all IFE can do (and mostly will) is slap a fine on the party that produced the video

What if they set up a DONATE HERE Page with two buttons... one that clearly says "Click Here to donate to TPB" and another one next to it that says DO NOT CLICK HERE OR YOUR MONEY WILL GO TO THE GREEDY MAFIAA.
I think that in that case users have a pretty good chance of claiming they hit the wrong button ;)

This guy has a name: Al Gore, so please give credit where it is due ;)
