I am reporting this for your ongoing site maintenance, I don't know that their is imediate action to take. This seems like an issue that might be just developing now:
I logged in to today to 68 or so notifications on my alert bell icon, so I opened it to find screen caps #1-#3, you can seee that as I scroll through the alerts it is only this one account upvoting my posts... but I don't have this many posts uploaded! LOL - this user profile "Zlaya Zaya" upvoted my post more times than I have posts, and when I click the link to see which post the page simply refreshses to my profile page on the albums tab (normal home page).
These are clearly fake or robotic. Potentially generally degrading to the quality of the site.
I love your site and I hope to help by reporting this activiy in the big picture.
