>Do you remember seeing your vote on steemd or any interface other than steemit.com back then?

I hate that I have to answer this no, which leaves room for multiple possibilities I am guessing from your asking. It never occurred to me to check an independent site as from appearances it did appear to take. I can however say with certainty that people do disappear as followers and from my follow list with their being no record that I was unfollowed or that I unfollowed on Steemd. Which would still indicate that somehow things are getting lost. Others have noticed this glitch with the follows as some of the comments and the one link I shared show. I am thinking for those with large followings this might never be noticed, or they just assumed that it was done intentionally. 

At this point I feel that we have went as far as we can with the data that we have in. I feel good that you are now aware that this might be an issue and perhaps will watch for it in your own dealings here. I looked up your blog and you seem really smart at blockchains and pulling data from the chain itself. 

I see that you are a mod for Utopian. I do not understand it (nor the other interfaces), but was curious. Are you a witness for the blockchain? If so, I wish to vote for you. Your coming here, looking into this for answers is exactly what a witness should do, and I thank you for reaching out.
