There's nothing wrong with that, wanting to make some extra cash. It's a matter of the source, if among the first things wanted is a bank account, watch out.
Even during the employment application process, after you're selected for interview, pass physical, forms for tax deductions & direct deposit for payroll (many companies have gone this route) are among the last things to fill out.
In an ideal situation, you should be prescreened for your qualifications before payment information is asked for. I haven't applied for anything like this, though I was interested in creating my own website to allow for Google Ads (this pays too, by click for pay). The ads you see on sites, that's how it works. Unfortunately, some ads are bogus & spyware/malware is awaiting your click.
Good sites will screen these out, but nothing is 100% guaranteed.
The reasons I backed out, is that first, the TOS (Terms of Service) of my ISP are residential use only. This would knock out the creation of a forum. Maybe a blog would be permitted, but it would have to be good to attract viewers (& any ads).
The second reason, is that I'm disabled & am required to report earnings. Not any work that I perform pro-bono (free of charge), but any that I'm compensated for. Gifts that I may receive down the road, in the form of "hey, I got a new laptop & am giving you my three year old one", or anything else where someone purchased something new & gave me their old, aren't considered earnings.
This is why I cannot have a site with click for pay ads. Dimes adds to to dollars. If an actual purchase is made, there's a higher commission involved. This is also a possibility for you, provided you're not in the process of a disability application, or receiving benefits. You can even direct solicit businesses to post ads on your site at no charge to them & you get paid only for Trial downloads & sales. The bonus to the retailer.....100% Free Advertising, unless someone clicks, and the retailer can offer a discount based on the free advertising alone. It costs lots of up front cash to advertise in publications & on TV....none on your site.
And the really cool thing, if a certain retailer is getting a lot of clicks from your site, enough to make a positive impact on their bottom line, you're in a position to bargain for higher commissions. They can say no....& risk losing all of that business, or an agreement can be worked out. You can sweeten the deal by doing regular articles (or reviews) of their products & regardless of whether or not you like the product (or even believe it's rubbish), create positive reviews of their offerings & tell your viewers "why" this product is great & "why" they should choose it (but don't overdo it). Of course, do your research & compare it to obvious inferior offerings.
Case in point: Many tech forums strongly advise against the use of registry cleaners. However many has ads on the site promoting them at discounts (though I haven't seen these offers here, I have on other tech forums).
Of course, for your reviews for products on your site to be credible, a name other than yours needs to be on the review. A friend, relative with a different last name, anyone but yours.
Being that you're using whatever connection you can get your hands on, this may be a no cost option for you. However, just like with affiliate marketing, don't expect to get rich overnight. It takes dedicated work to create a site, to attract viewers, and to get companies to place no cost ads on your site. Some lesser rated companies may be more willing than a top notch one, whom wants to be careful of their reputation.
I once had a friend in Australia that had a blog loaded with ads for all sorts of products & services, you name it, he had it. Unfortunately, we've lost contact & I don't have the link to the site, plus it would be seen as spam on this forum. But the main page to the blog, was covered from wall to wall with ads. He covers a lot about Microsoft & the tech industry in the blogs & actually has an award with the corporation. It's been awhile since we've connected though.
Anyway, the money is out there, you just have to find it.
