They are basically just editing a screenshot of whatever show they are watching and just change the headlines after. With all the available tools that we have right now for photo and video manipulation, it's fairly easy to do such and fool people with these edited pictures. Tons of those advertisements can be found on Filipino forums, Facebook pages, Twitter and whatnot. Whenever I have the time, I try to report all such posts to at least help notify these sites from the scams. Heck, even in Canadian, Thailand and Vietnamese forums would you see the same type of thing! That's why sometimes I'm thinking that it's better to filter cryptocurrency ads on Google or any other large websites that people frequent in order to minimize the number of people being scammed.
Internet has made it possible to spread any news to a greater extend which almost covers most part of the countries. These people who were behind this scam might have some education qualities like digital marketing, graphic designing, etc which made them to convince other people that whatever they are publishing in 100% true. These might be some talented people not using their talent in proper section. They deserve to be under the bars because they would seriously harm a lot of people financially.
Social media, google advertising allows a lot of promotion no matter it leaves positive or negative impact on the community. Social media itself would help these to spread to the major extend.
