I think I've found a solution to this problem: finally.
You have too many curation trails selected. What I did was go through and delete all my curation trails. I then found one that keeps an average of around 83% for its followers. I did this several hours ago and I've not had to go back in and re-enable it thus far.
I believe I just had it set to vote way more than my account could handle. Which would obviously trigger a fail-safe.
Hope this helps.
I am not sure if that was the problem. It went away after I received a small piece of delegation from a friend.
