If these are supposed to be used for hammocks, I would expect there to be hammocks in the photos, not just poles. If they haven’t put the hammocks in place yet, say for the summer, you may need to wait for them to be put out before submitting. If the hammocks are not permanent and those living in the neighborhood have to bring their own, it’s going to be a hard sell without a hammock pictured. This is most likely why ML rejected them, as ML doesn’t see these are spots where one could possibly socialize, just some wooden poles in the ground.
Also, I don’t see any slacklines for one to practice balancing on, which would allow for some exercise. Not having the slacklines be permanent could also be seen as an issue. Personally, if I was voting on these, I’d most likely reject since there are no hammocks and/or slacklines between the poles.
I think these fall under a grey area, since they can temporarily be used for certain activities, but what makes them permanent (the hammocks/slacklines) are temporary. If you can provide a link that notes that the developers added these for these purposes, this would be helpful in showing what they are.
We get 2 appeals every 20 days, and not everyone even uses their appeals. I rarely do, so I almost always have my 2 appeals available. The burden of proof is on the submitter, and if the submission is lacking info that can lead to issues.
You may want to take some time and look over the suggestions and info that others here have provided you about some of your nominations. Not everything is to be guaranteed to be accepted, whether by the community or staff, and some of what you are submitting fall more in the grey area and/or hard sell area.
I will say that what has helped me quite a bit is actually reviewing nominations, as then I get to see the good, the bad, and the just plain awful. A really great nomination may take me less than a mintue to approve, while good but not great may take longer, as I may have to do more research about them. The awful tend to just be ineligible, like those located at K-12 schools or generic businesses, or issues with accuracy, such as a 3rd party photo being uses as the main photo. Reviewing has led me to be much more thorough in my nominations, and has given me many ideas of what may or may not be eligible, since, again, nothing is guaranteed to become a Wayspot.
