I disagree about the cryptocurrency community, it is already very large and is constantly growing. Yes, you can make several coins with the same name, but what difference does it make if there is only one cool project of them, and it can be easily distinguished from scams?
We do have such scam projects as well along with some of the best projects and need to do through research before investing in any projects. If not able to distinguish and feels can lose money then do invest only in the best of the projects which are listed and has being doing well and will continue to rise rather than investing in projects which are uncertain and could turn out to be scam.
