One of the companies you are advertising is closed, check the list! Next, I think it will be useful to explain to everyone how you chose them according to which quality, because it is simply not reasonable to choose a company on the payments, you need to evaluate the idea, the team, the site, the WP. Also, I think it's right, we need to find every member of the team in the social networks , to find out whether this is really not a fake page, to communicate with the administration, to know the opinion of experts. You can certainly move this list aside and choose a company for payments without understanding the project. But this way if the company turns out to be a fraud, then you just help to develop such companies, there are already a lot of them, all because people thoughtlessly invest in the scam hoping to get money.
