I have noticed lately builders getting lots of flack for getting upvotes on builds many consider to be of lower quality, or individual builds getting mass reported just because they went "viral" despite being cheap meme builds.
You should understand that a builder doesn't decide how many upvotes his post will get. People like what people like.
Furthermore, this is a game community. We come here to enjoy the content, not to be annoyed by unnecessary drama.
Help the builds that you consider well-made to gain points by upvoting and spotlighting them, maybe by sharing them on Discord. Don't try to humiliate builders whose work you dislike.
Another issue I have noticed is that peoole tend to get annoyed when someone doesn't accept their feedback and suggestions. Magic of SimplePlanes is that everyone can play it the way they like, don't force your preferences onto others. Some of the builders I like have stopped building due to the pressure from the community, while many have entered arguments over that. Build your build, provide feedback to others, but don't be mad when your feedback is not integrated into the build.
