I appointed several wayspots through Pokemon Go. They are disc golf holes, which meets Niantic’s own standards (exersize equipment). However, they have all vanished in the last week. How do i address that? They all met criteria, so there is no valid reason why they should have been removed after appearing as pokestops. Yet, niantic seems to have 0 in the way of contacting someone to fix this situation. What am i supposed to do? I do not have twitter and will not be making one. How to i get my pokestops back??
Welcome to the forum 
They were incorrectly accepted, and correctly removed as duplicates.
Please see Golf & Disc Golf Courses
Please take this on board and do not resubmit these or any other individual golf holes/tees/etc. One wayspot represents the entire course.
IF these were eligible, there are avenues to request reinstatement, but these are specifically not eligible. Requests for reinstatement with evidence can be made in Wayspot Appeals or through Request modification or removal of a PokéStop or Gym — Pokémon GO but don’t ask for these to be reinstated and do not resubmit them, as that could be considered abuse.
