Heisei Democracy compiled a list of scandals and mishaps in 2007 anime. It looks pretty thick even with the year still to run out. Check this out:

Darker Than Black: The show’s production manager ran away with the manuscript.

You just can't make this up.

Gakuen Utopia Manabi Straight!: Due to complaints about the scenes of school graffiti in the OP they were altered in mid-production.

Truthfuly, the graffitti pissed me off livid too, but Manabi is still one of the 3 greatest series of all times, so I was silent about it until now. I do not remember any changes to the OP though. Maybe fansubbers boycotted it and mixed episodes with the old OP? I'll see when I get later R2 DVDs.

I wonder how much of this is due to the increased exposure of both the shows and their creators online… it seems like a lot of these incidents would’ve gone unnoticed in the pre-internet age.

Indeed.
