Please examine the two screenshots carefully. Although they share the same name, profile picture, and cover picture, one is authentic while the other is fraudulent.

To determine the genuine account, look for the presence of friends, followers, and accounts being followed. The legitimate profile has a notable number of friends, followers, and followed accounts, whereas the fake one lacks these indicators.

If you encounter the fake profile, I would appreciate it if you could report it to me.

Additionally, be aware that all my official posts contain my text number, 605-351-7831. If this number is absent from an advertisement, it is likely counterfeit.

Furthermore, I never request deposits for parts.

Thank you for your cooperation.

Sincerely,
Greg
