This is very interesting @transisto. I did a post the other day on @freedom, also looking at the data, but in a very different way.
I had noticed that @freedom had removed delegation to paid upvote services, but I did not look at how delegation was being use by the new people freedom delegated too. I noticed that @spaminator and utopian-io were on the list, which are worthy projects.

Removed from two, added to another. Then added to a lot of spammers.
@utopian-IO is very worthy, not a single self-upvote, and the bot's code even penalizes posts promoted via booster bots for self-upvoting purposes.
I've been watching but not posting about the re-delegation, because I wanted a slice for myself - although not to self vote or offer a pay for vote service i should add!
