mine was accepted but its been almost 3 weeks and its stil not there? Why
Welcome to the community. Can you tell us a little more about the nomination? The name of it and the GPS Co-ordinates could help us. One possible reason is that your nomination exists in the same cell as another wayspot. Read up on https://pokemongohub.net/post/article/comprehensive-guide-s2-cells-pokemon-go/ which explains a little more about how the community understands how the Wayspots are accepted into Pokemon Go.
