President Donald Trump retweeted an apparent fan Saturday night. The fan received the RT from Trump after posting a photo of the president with the caption, “Trump working hard for the American people…thanks.” Trump returned the gratitude.

It seemed like an innocent enough exchange. Shortly after the commander in chief bestowed the RT on the user, @ProTrump45, however, people started questioning the legitimacy of the user, whose name is listed on her profile as Nicole Mincey.

As Salon pointed out, Mincey appears to be a Twitter bot with an account set up to sell pro-Trump merchandise.

Bob Schooley, a screenwriter and TV producer, investigated @ProTrump45 and exposed not only this account but also others that appear to be bots that were set up to show love to Trump. These numerous accounts appear to have taken and altered stock photos from the same website.

Schooley’s investigation yielded an informative thread.

So the person Trump retweeted today that's accused of being a bot. She joined Twitter in January, a full blown Trump believer. — Schooley (@Rschooley) August 6, 2017

This "profile" of her quotes from a Daily Caller piece...https://t.co/JGhu6s8WhT — Schooley (@Rschooley) August 6, 2017

... which is apparently an advertorial provided by "her."https://t.co/Ry7Ij2ImGG — Schooley (@Rschooley) August 6, 2017

I didn't see any real autobiographical details, such as college name or parents name. — Schooley (@Rschooley) August 6, 2017

There's also this person promoting her, who claims Buzzfeed on her bio, though she doesn't have any pieces there.https://t.co/2Ad8F6Y5e4 — Schooley (@Rschooley) August 6, 2017

Something's a bit odd about her bio shot. pic.twitter.com/AYJtiiUNCY — Schooley (@Rschooley) August 6, 2017

What's really cool is when the bots complain about fake news. pic.twitter.com/e0fLJUe48U — Schooley (@Rschooley) August 6, 2017

Literally dozens of these memes on this bot account. pic.twitter.com/i4k31mrrZi — Schooley (@Rschooley) August 6, 2017

Most of these accounts tweet each other. It's hilarious how many use the same T-shirt models. https://t.co/0AhpjACMHp — Schooley (@Rschooley) August 6, 2017

Never let it be said that Trump doesn't have diverse fictional followers. pic.twitter.com/qbt7UdmOpK — Schooley (@Rschooley) August 6, 2017

It's not so much these fake accounts exist, it's that outlets like WND and Daily Caller give them legitimacy by writing profiles about them. — Schooley (@Rschooley) August 6, 2017

The takeaways from this story: stay woke. Though we have no idea whether Trump was aware this account is (probably) a bot, wild political gesturing happens everywhere, even Twitter. Don’t believe every surface-level tweet you come across.

And, if you happen to be a stock photo model, there is a chance you’re being portrayed as a Trump supporter on Twitter.
