If the bot didn't have so many different people's SP delegated, I don't think they would need to put restrictions on how it is used. They are simply trying to avoid using other people's voting strength that was given to them to possibly upvote something they wouldn't approve of.
That isn't censorship, it's merely being fair to all the people who sent SP to the bots.
@aggroed himself removed all his flags in a flag war when he realized it caused that account to no longer have the ability to post. He hates censorship. You are wrong to accuse him or the MSP community of that.
