Weird DM's from people in the subreddit

Anybody else getting weird DM's from random accounts that are joined in the subreddit? I've gotten a few that are spamming me about how I need to "stop harassing the twins" and shit like that. I can't tell if the accounts are Niki and Gabi or if they are legit fans, one of them is an account that is assumed to be Niki, but I've never heard of the other two accounts dming me being her, I've only seen their posts here praising both of them.
