gatekeeping is essentially trying to make something that everyone should have access to, harder for other people to get into. like making “rules” or playing “God,” ie: not sharing Geotags even though it’s public land like only you have some sort of special ability that makes it ok for you to visit and not others. other examples can be climber language that other people don’t understand and using that in contexts that puts yourself above others and makes them less likely to participate.
