You'd like to know why we require X number of posts to request a file?
Short answer: our house, our rules.
The in-depth answer isn't that complicated either. It's really as simple as not wanting our Requests forums to be flooded with topics by users who signed up a few minutes prior. Content isn't on-demand. We want our users invested in the community if other users are going to assume the risk of acquiring and sharing that content on their behalf. WebFlake is a peer-to-peer community. We don't require donations nor do we demand content in return but a few posts is a small ask in comparison to the tremendous amount of free content available to you.
Engage in community discussion. Participate in off-topic forum games. Answer a support question. Share a useful tutorial. There are several options available to you to achieve those fifteen posts in a short amount of time.
If that's too much for you, well, then it's too much for WebFlake to invest in you either.
That said, you mentioned in the topic title (which I've changed to better reflect your question), that you are looking to "hire someone". Our Requests forums are strictly for file requests. To hire someone for freelance work, you'd need to use our Marketplace. The post requirement for the Marketplace was recently lifted and in its place, new restrictions were added — as outlined in our Release Notes, which Hidden linked to. You'll also find a brief description in that release, for why these restrictions exist.
