Have been thinking the same thing.
At first I thought it was just my account on my wallet, like this was a peek into my next update of my reputation - eeeeeek
But then I too noticed it on other accounts when you go to the wallet page. Very bizarre, haven't read anymore about it though.
yes, and with steemit being decentralized I don't know if there is anything to do or who to report.
Go to https://github.com/steemit/condenser/issues/new and submit the issue there :)
thanx for letting me know!
