A Florida TikTok personality who describes himself as a “demonologist” and “Grey Hat Hacker” has been jailed again after allegedly posting women’s private information and claiming he could monitor their movements through their phones.
Mark Stephen Asea, 36, of Port St. Lucie, was booked into the St. Lucie County Jail on Sept. 30 on a felony charge of offense against computer users. Sheriff’s office records list his bond at $35,000.
The arrest reopened a case that had been closed earlier this year. Asea was initially arrested in April on stalking and computer-related allegations, but prosecutors dismissed those charges in May. A computer-access charge was filed in September, according to court records.

According to a police affidavit, two women told investigators that Asea had revealed their personal information in TikTok content. One of them said she had previously relied on him for help with a computer issue.
A detective reviewed a video in which Asea allegedly recited information about one woman’s devices and said he knew about her recent purchases.
“Let’s talk about your actual password,” he said, according to the affidavit’s transcript.
“How about we talk about the last 10 purchases you made online?”
The woman told police that she had shared the password only in a private TikTok group chat. Asea was not listed as a member, she said, though she believed he could have accessed the conversation using a fake account.
She said no one in the group had permission to distribute the password and told investigators she had no idea how Asea might have obtained her phone identification number or banking details.

The second woman’s concerns began after she sought what she described as ordinary technical assistance.
She told investigators that Asea remotely accessed her computer in October 2025 to help fix an application. Months afterward, she said, he claimed he had secretly installed a virus while she was in the bathroom, giving him the ability to view information on the computer without her consent.

She told police she had never authorized such access.
A photograph from a private Telegram conversation on her phone later appeared in one of Asea’s TikTok posts, she said.
Asea allegedly claimed in a comment that the photograph had come from a WhatsApp exchange. The woman, however, gave investigators a screenshot showing the image in the Telegram conversation, according to the affidavit.
Police also recorded statements in which Asea appeared to boast that he had determined the woman’s location using her phone.

“Thanks to the GPS within her phone, but what did I do?” he said in the video, according to the affidavit.
The alleged posts piled up. Investigators said Asea uploaded more than 100 TikTok videos mentioning one woman, sometimes posting as many as six in a day. He also allegedly obtained a website where he posted a photograph of her getting a tattoo.

His TikTok biography lists “Demonologist,” “Clairsentient,” “Empath,” “PTSD,” “Grey Hat Hacker” and “Woodsman.”
The April affidavit documented a different account biography that included “former satanist” and “cybersecurity engineer.”
Asea also faced a separate civil stalking protection case over the summer. A woman obtained a temporary injunction in July, but a judge dissolved it and dismissed that case Sept. 8.
Prosecutors reopened the criminal case Sept. 24 and filed the current charge alleging unauthorized access to a computer or electronic device. The records provided do not explain why the earlier charges were dropped or what prompted the renewed prosecution.
Months after the original charges were dropped, Asea is again facing a felony computer-access charge. He is scheduled to be arraigned Nov. 19.
