Weird notifications

I've been getting these weird notifications from tiktok for like over a year, I only have one repost on my main account and none of my alts have these reposted either, the notifs are usually in polish, I do not speak polish nor have I ever been there, the accounts are random people I don't know or follow on any of my accs, though they often repeat, these notifs do not show up in the tiktok app
