What's the catch? Plan on throwing a bunch of ads up to try and make some money or u just a generous guy?

Its actually a school project. I am a Computer Engineering major and we had to develop a system which used what we have studied (MySQL, HTML, PHP, LAMP Stack Servers, various cryptography practices).
There are a few ads on there to help offset the hosting/mining costs, but I'm not looking to quit my full time job
