More reasons:
The Producers are bored and nip out for a Pint for 30 or 50 minutes so hit the censor button before they go!
The one about "saving" clips for highlights is absolutely true, anyone who watches "live" fee and HL can tell you that what was censored was for no good reason, other than to make the HLs more interesting.
They employ trainees who have no idea what is allowed so just censor anything and everything.
