I'm not worried about it from a normal usage standpoint. The website isn't interactive, I plan on being the only person with edit privileges on the wiki, for example. But I feel like based on things I've read, mostly on HN over the years, that this is opening a...different sort of box of worms than I already have open. Easier DDOS? Abuse of my image hosting, killing my monthly bandwidth allotment? I really don't want to have to set up a CDN just to host a wiki that is averaging less than one not-me viewer per month...
Am I paranoid, or just uninformed?
