My personal rrat, as quickly as I can:
Vesper canceled a stream because he was locked out of his "account." Don't remember if he said it was a Google account or not.
Vesper and Magni did that off collab a while back. The naked PC building one. One of them took down the others IRL personal information and kept it somewhere. Likely on an electronic device. Likely Vesper.
Vesper lost the electronic device. Someone found it, got into it, started rooting around. They recognized some things, realized they had something special...and were nut jobs or malicious in some way.
Vesper and Magni are both on long term break with hush hush info because they're dealing with something screwed up. Stalker, blackmail, whatever.
I only make these assumptions because of it involving his tech/password getting messed with, and personal info there may have linked him with Magni IRL.
