Along with the Criteria Clarification Collection, you will also want to review the Wayspot Criteria section in the help center. How to Review Wayspots is also another good section to check out, as it gives info on what makes for a good title/description/photo, how to place the location pin, etc.

Keep in mind that you cannot base your nominations off of what may already be in-game. It seems that some of what you are nominating may be based off of imports, especially for Power Spots, but imports do not have to follow the Wayfarer criteria. Criteria also changes from time to time, so what once was acceptable in the past may no longer be, but there are still Wayspots out there that don’t meet removal criteria.
