::::::I stated my belief that you are not a WP:Newbie, just like I did with an editor in a different recent case. Are you claiming that you are a WP:Newbie, despite not editing like one? Are you claiming that you edit like a veteran who makes occasional mistakes because you watched the Wikipedia process for so long? A WP:Newbie would not make this edit as their first edit (and they typically wouldn't sign their username for their first edit); they also wouldn't state, "While WP:SLANG is an essay, it represents an uncontroversial community consensus which should not be disregarded lightly." How do you know what is community consensus on Wikipedia? As for filing a WP:SPI, it takes time sometimes. Sometimes I have to take days or weeks to gather the evidence and not the similarities between accounts, the way new account is trying throw me off his or her scent by changing their editing pattern, and so on. In other case, it can take a year, with the WP:CheckUser data being stale, but the behavior data being strong.
