Well just some advice from one developer to another people are intrested in your concept but at the moment it doesn't work because there is no certainty that the image is what was promised. my recomandations are:
Create a way for posts to be verified
when the user is uploading ask them premission to verify if the picture is original and you can view the image and perhaps also do a reverse image search to see if the image appeared elsewhere. if you've decided the image is original you give it a green badge so people could have more trust to send funds.
When building unpix.in I didn't wanted to create a user/picture validation system like reddit's GoneWild. Reasons are:
It needs registered users:Adding this needs working pages like registration/login/reset password etc. That moves unpix.in from "easy and simple" concept, which is too important to me.
It needs adminstrationI (or someone) need to check if user is valid, post is really giving what it promise. It's a lot of work, I don't have time for this.
So... that "trust" problem can be solved simply tipping the posts which you know the sharer of post. If Kim Kardashian shares a link from her twitter account and says that "here is my boobies" you can trust her and tip for example. Do not tip post of a bitcointalk user whom is appeared 4 hours ago.
I think scammers will try unpix.in but in time only good posters stay motivated, others will leave the area in time.
The website needs a comments section or chat
the website is kind of a community website as I'm sure one person won't send all the funds to reveal a photo for everyone else also to view. So you need a chat to build a community around the website so it doesn't feel like you're the only person on the website anymore. This will increase the efficiency of campaigns and also give you a stable userbase.
there you go, some free advice.
There's a subreddit that people talk, but may be I can add Facebook comments or diquss comments. Good point.
