Unauthorised Outgoing Votes!?

I just noticed that there are some weird votes going on from my account, some that I for sure have not done. I have not set ANY autovotes to anyone from my account, I only do manual voting, but now I'm noticing votes I have not done. I actually did notice this a few days ago already, but brushed it off as me not remembering that I had voted, because I switch between phone and computer, and throw votes to my fave people pretty blindly if I have extra VP left.

I checked my feed just now, and noticed that I had already voted on @tarazkp's newest post with 15%, even though I am 100% sure I have not done so manually because I wasn't on my computer, nor my phone at that time.

I started to go through my outgoing operations via Steemworld for the past couple of days, and noticed quite a few votes that I have not done manually. I know this because I never vote Taraz with as little as 15%, and @kommienezuspadt ALWAYS gets 100% vote from me, instead of the 50% I saw outgoing a few times, and I wasn't even awake at 8.10am this morning when the vote went out. I even double checked Steemvoter to make sure I have no autovotes set up, which I don't because I haven't messed with that stuff since trying it out for a while aeons ago and I'm pretty sure it didn't even work.

Wtf is going on in here and should I be concerned!?

Granted, all the votes that I did notice that have gone through without my manual authorisation, were to people I would vote on manually too, so it's not that big of a deal, but us being here on the blockchain that is big on security, it is a little concerning what else could happen.
