SB - let me into a little secret: very few IFR pilots ever look at notams. You check the weather, file the flight plan, and if the FP isn't refused then you are "good to go". That's how it's been done since IFR was invented and that's how most old hands still do it.
If they prosecuted everybody who filed an IFR FP, which was not refused (despite the fact that the ATC at the destination has it on their system within seconds of you getting the ACK) they would be nicking the majority of bizjet pilots.
