Everyone hates on 500px but it's probably one of my favorite photo platform.
Of course there's a lot of shitty content and spammy comments, albeit less than on the gram, but there's also tons of great photographers and people genuinely interested in your shots.
You just have to filter out any sort of glamour photography.
What I really appreciate about it is that they actually seem to listen to community feedback and cater to people actually interested in photography. They've done a lot to fight spam and bots, added filters for NSFW content and refined their discovery algorithm.
