This question already has an answer here:
I'm no longer able to post questions on Meta. I get the "We are no longer accepting questions from this account" message. I have a large number of downvoted questions here. Well, actually, there were only two such questions, but I'm not arguing. It is a fair deal. Like in aviation, rules on stack exist for a reason.
I'm asking to be warned about such things. I've seen dozens of different informational banners and popups on Stack Exchange sites. They provide help, inform you about/explain something.
But I haven't seen a warning like I describe. It would be nice to have one. Or not?
