I understand what you mean,
but do you know...! about blocking crypto ads by social networks like Facebook and others that aim to protect users from fraud, and at that time I also saw many fake projects that raised funds and after that they disappeared.
this is the main point that many people do not want to notice, besides facebook have a owner and the owner has the right to do whatever he wants, the owner of facebook also has a duty to respect the laws of governments. Facebook is a business that needs to generate profits and have a good reputation with the governments, they will not risk losing profit and reputation because of scam projects
