They obviously only do so because of her connection to iDubbbz. She has nothing of worth to her name beyond that (other than somehow cucking iDubbbz so brutally that he was willing to take her name in the marriage, even though he's more famous and the only talented one of the two).
And iDubbbz, despite disowning his "edgy" past, only still gets people to work with him because of the reputation he built from said edgy videos. If he really disagreed with everything he said in those videos, why aren't they deleted or at least unlisted? The only one that ever happened to was the Leafy Content Cop, but YouTube themselves deleted that one, due to their gay harassment policy.
Answer? They still make money. Clearly, his "principles" aren't that strong.
