I have voted on content in the past, when I used steem regularly, which as you note, was a long time ago. However, the only reason posts of mine are even appearing right now is because I'm trying to sort out DTube to archive old videos I made years ago.
I'm not taking anything, my own upvotes shouldn't have generated anything noticable for me and there's no reason for anyone else to upvote it either, considering it's all clearly old videos. I will upvote things when I actually browse posts, but since discovering hive two weeks ago, I haven't yet done so, in fact, your remarks are the only thing I have read on this website so far.
