I'm getting A LOT of emails with this. Same content, same link. I click the link, a web page shows me my previous mail for discourse (signed up via G2i, have since been switched to using my actual mail address) and then I get an error page with

I submitted a ticket via the AI "assistant" and now I get the same email more frequently, PLUS one welcome email as if I had just signed up...

Is the platform going haywire?
