If looking for tokens which launched without ICO/IDO or anything else just join a telegram signal group which have that service for people, in case there are no other ways you can get source of information, if the project have ICO/IDO or anything else like that, just join it but usually need some requirements to do that, in my country there are a group that offer service so their member can be participate in an IDO of a project.
If only you're really in a group that has some good signals and strong on what they promote but if you're into group that just promote a pump and dump coins/tokens expect the worst case scenario.
