What happened to the red X option

As much as some got so upset about the X, this is a technical forum. There's gonna be wrong answers that require an X.
Egzactly.
Some of us used it for a red flag warning on a post that had something technically very wrong.
Something that could cost an reader in a big way.
The explanation is of course warrented, but might not show on the same page.

example, describing the black wire connection on the ammeter as negative.

Make the X black if that's less offensive, but for the forum to be a better source of info than FB or youtube, there should be a way to throw a reader warning flag.
