> Would a HackAfrica event having nothing to do with African problems be appropriate?
Yeah I would imagine that would just be a hackathon taking place in Africa.
Unfortunately, I think you're just causing a stink for no reason, and you're not too familiar with the undergrad 'hacker' culture.
Take a look at these names and tell me which ones you don't like: https://mlh.io/seasons/f2015/events
Something tells me it will be a lot of them.
