Some of the members lack the option to choose from, they promote projects hoping that the project will turn out to be good after the market gets better, and on leadwallet, good projects have no nationality, even if they are all coming from one country, as long as their project is not on the scam thread they are still ok to run crowdfunding, it's still in the hands of the investors.
Its up to investors who will be the one to invest them and bounty hunters must try their best to promote the project they participated. Some newbies today are just participating without any background check about the project and how much campaign will they participate in social media. Today, only few projects are taking seriously to launch their token and a lot of them just purpose is to scam others.
Hundreds of projects are planning to advertise but only some are really serious with the original plan. I think based on what is happening in this market, we cannot blame them because covid-19 is making the situation worse and if not sure, do not participate because it only makes for you more time consuming.
I always check many times before joining and always have a reasonable strategy to ensure the project brings me money.
