As I understand some major players in marketing like Facebook, Twitter (even google if im not wrong?) etc haven't really allowed any blockchain related campaigns go through since January. How are new projects surviving now and reaching out to people who could possibly interested in what they have to offer?

I guess one way is to advertise your project on this forum and then hold Airdrops but is there anything else that a newcomer can do when we leave out places such as cointraffic etc that will charge a lot of money.

Btw, not planning on starting a project myself, but as I have somewhat background in marketing it's just curious what has changed in marketing blockchain projects within the last year really, because it seems like a completely other area and there are so many restrictions.
