weird tiktok account

i dont really use reddit and i dont know how to make a post on here or if this is even the right place to post about this but like this has been on my mind like and i need to figure out whats going on here. basically i was scrolling on tiktok and i came across this post of this woman like jut posting herself to a weeknd song without lipsyncing. something about the video just made me want to see her account and i saw that she was posting her face to the same few songs over and over again but she was using the same clips she has has in previous posts. i was a little weirded out so i checked out her reposts and they were normal reposts. then i went to check her followers and thats when i saw a bunch of accounts with her as the profile picture and usernames such as “byamorisasassydiva” and more usernames along that line. i checked out some of the accounts and i saw they were posting the same videos as the first account was and some were private. the further i scrolled the names got weirder like “byamorisgetthingloud” (i mean that one isnt that weird) and byamorhasalotofsocialmedia” and the weirdest one in my opinion is “byamorisgetthingloud”

anyways i was like getting more and more weirded out as i read this names because a common pattern was saying how she was an adult and grown up. i requested one of the private accounts just to see what would happen but my biggest concern is that people are taking this womans posts from her actual account and making spam accounts and just mass posting these, but like i dont even know why they would do that unless they are like making fun of her? she doesn’t seem ai generated and looks like a normal person but like im really freaked out

(after writing this out i checked out her youtube and its literally just a normal girl making posts on youtube. i honestly am concerned for her because these account names are all about her looks or her age and thats like really weird. i dont think she knows this is happening or is like apart of this i feel like it might be trolls but lmk what you guys think)
