Unlimited is certainly a marketing term and I am not against it per say, however you are running this from a 20GB Digital Ocean with access to 1 core and only 512MB ram. To get up and running it's maybe going to hold out however the abuse level is ridiculously high, it won't be long before you start getting someone abusing the service and when they do it will likely only take 1 to kill the service whilst your sleeping.
You can throw around the fact it's a free service and you cant provide high uptime or entirely prevent abuse. This is true. However the 1 in 50 genuine signups you get are the ones you want to keep and need to keep on your side. You can't do that unless you have the setup to cope with what is ahead and you simply don't.
It seems to me like you have some credits at DO and are testing the water, once the credits dry up and you are not making anything from it but hassle you will fold it up which really won't take all that long.
A youhosting provider would probably be better than this service and it takes a lot for them to achieve that kind of accolade. In fact there are many free providers out there and compared to them this is nothing more than a cobbled together service.
I get your enthusiasm and applaud your determination to keep trying however I can only see this ending up in the failure bucket of projects you are connected with. I am sure there is a talent within you that would be better to focus on than hosting but I don't know you well enough to know what that could be. But I suggest you take a step back once you realise this is going nowhere and think about what you could be really good at and work on that.
