Mastodon is slowly gaining popularity, but it also attracts bad actors and scammers. Remember that no verification or blue tick mark is for sale on any instance. Similarly, be aware of popular accounts getting cloned in some other cases. As usual, all of these scams have one goal: to steal your information, money, or cryptocurrency, or get you signed up for OF, etc. Stay on guard and report such accounts or instances.
@nixCraft Granted, there are certainly legitimate people out there that use OF for income, but if I were to get spam replies/PM's asking me to sign up to one randomly and has no relevance to the content I post, than I know it's more than likely a scam (or they could possibly just be stealing content from elsewhere on the Internet and reposting them to their private OF followers without the original creators knowing, who really knows).
