They did not tell me that.
Moreover, as you mentioned, the Adswage platform doesn't seem to have any social media links or usage/terms policies. Also, no YouTuber reviewed the platform and spoke about its legitimacy, and the reviews on Trustpilot are likely to be shill reviews
[2]; if you mean the platform domain that ends with .com.
It's a recently launched platform, not even two months old, and the Admins are transparent about it with the users. When I asked, I was straightforwardly informed that the platform is new. For social media pages, you can find links in the footer. As for terms and conditions and other pages, they're available on the website, but you simply didn't bother to go through them.
There is no need for a deposit but in general you pay small amount for ads advertising in legit companies.
You sound like you might be new to the internet. Adswage isn't the only platform that requires users to pay fees to participate in their earning program. Twitter, Distrokid, and many other platforms follow a similar approach. These fees are typically in place to safeguard the platform against scammers who might exploit the program by creating multiple free accounts.
Now, I'd like to ask you: How would you propose preventing referral and bot fraud in such a program if it were made free for everyone? Consider why platforms like Twitter and Distrokid charge users upfront. Why do they not deduct fees from your account after you've earned money?
This platform is legitimate, and I challenge you to provide any evidence of being scammed if you claim otherwise.
