I personally use vgy.me[1] because I like their privacy statement[2] and never had problems with them (so far) but that mostly has to due with them also not having the same reach as imgur
vgy.me is also pretty fucked.
I tried using it a few days back after the Imgur chaos, but had the image showed up a proxy error. Turns out, the image had even been deleted. Not sure why. Also, I think vgy.me is one of those service that will disappear overnight due to It's less popularity. Now, you don't want your 5 years of screenshots disappearing overnight.
