It strikes me as a term where everybody thinks they know what it means but if you drill down most people just made up their own definition and there's no agreed-upon definition. While everybody agrees that toxic users are bad and you probably should get rid of them, many would really disagree on who the toxic users actually are. My made-up-on-the-spot definition would be: "Everybody who hinders business interests." May it be by hindering user growth or even causing user loss. For example making large groups of users feeling uneasy in some way. For example using bad words or posting bad ideas or even purposefully provoking users or user groups. Or by hindering revenue streams for example by advocating ad-blockers or making the advertisers or other money sources feeling uneasy. Or other reasons.
