Article about it.

TL;DR- She's been acting very unnatural in videos the past few months, seems someone is directing her in them, bruises on her arms, and in one video you can faintly hear "Help me."

She was supposed to have some sort of meet up tomorrow in a few days in the UK (at 6:30 AM UK time). Lots of people online telling others not to go and to let the cops handle it.

Check out the hashtag on twitter #savemarinajoyce lots of Holmes work going on there.

Some reddit threads on it from /r/youtube and /r/BeautyGuruChat

Edit- Cop account has said she's safe, expect lots of drama if this comes out as fake

Edit- She live streamed this morning and tweeted a bunch of the same type of "I'm totally fine" replies.

Moments of the livestream are still really weird
