Honestly? Not really. It's an open forum, I don't think it's really ever good form to tell somebody "hey, you're not supposed to talk about that here." (unless it's spam, in which case, just downvote. Saying "don't talk about that" is off-topic and has been specifically addressed by PG in the past.)
I'm sorry I didn't know that you had an alt account, it's just annoying when people start showing up and trying to dictate how things "should be" to established members of an existing community.
