It's becoming an increasingly bad time to be hosting anything on your own, having to worry about whichever 0-day the clankers are going to find and/or exploit within minutes of it being patched. I'm not sure even nginx is safe in all of this. I used to think there was software that should be basically safe but I'm not sure hosting anything (open-source) yourself anymore (i.e. directly participating in the Internet on a personal level) is a good idea.

Having to go through 3rd party services (and rely on them to stay on top of things) to participate is not fun.
