In my experience, I use Twitter with multiple keywords based on hashtags. Another way, I joined Telegram group, but this was not just joining the telegram group from stranger, but a group where one of my friends knew the members and quality of the group. However, this way does not guarantee a 100% legit project. so you have to be careful if you follow the channel/group/socmed account early tokens/project. The worst thing is that you are trapped in a token scam that compromises your address.
