Infuriating corporate technical support forum anti-pattern:
1) Someone posts a sensible description of a problem they're having.
2) Employee replies "The forum moderator had marked your post as needing a little more investigation and direct support. An online support case has been created on your behalf, please stand by for just a moment and you will hear from us."
3) This gets marked as the Accepted Answer, and seemingly will never be updated again.
... all the downsides of a public forum, plus all the downsides of providing support in private channels 🤦♂️
