I couldn't find any reason to still be getting notifications for certain tasks. ClickUp Support informed me that because the tasks are being created using a form I created, I will always be a watcher. This is silly and problematic for any team that shares or shifts responsibilities. (Create a form, set to public, share with stakeholders, hand off to new employee when roles shift: you'll still always get added as watcher when customers/anyone use the form.) Someone else could make a new form, but then you'd have to share a new link with customers (which looks unprofessional, especially if responsibilities rotate).
The workaround of setting an automation to remove yourself as watcher doesn't always prevent you from getting notifications, and creates more clutter to keep track of.
PLEASE turn off the "feature" of "the user who created the Form view will always be added as a watcher to tasks created from it."
Make it a toggle on the Form settings, or allow ownership of the form to be switched (This is already a feature request), or something, please.
