At the start of the new year, I encounter an area with a few pokestops and a few gyms, so I decided to help this area by submitting 50+ pokestops (and continuing). The result is quite amazing for only 1/3 of the way.
If you want to submit pokestops, do read the wayfarer criteria and learn how S2 cell rule work. It is amazing when your submission get approved daily.
