Transcription: picture is a screenshot of a user inbox page with a new message containing a photo of a woman with dark hair. The message reads "Hi I am Nicole but you can call me the Fediverse chick". There's more text but this is very obviously a bot attempting to get people to join a particular server.
On a side note: I can't delete this message as I get an error about dms not being available. I've blocked the bot already. Does programming.dev support dm's?
Best guess: it's like the innocuous "wrong number" scam or the looking for love email scams. Talk with "her", form a "friendship" or "romance" until she has your trust enough to sucker you into buying whatever scam bitcoin or sending money.
