Very safe for me, I find nothing wrong, just some mean ads that now stopped showing up and now I no longer have issues here. Please use an adblocker if you want to let your children use this site and check what they read, the comics they contain can be for kids but can be mature comics as well.
I find it reliable enough. Though safety, I'm not 100% sure about but then I'm suspicious of most sites like these. It does hit me with pop up ads quite often as well as attempts to redirect me to who knows what other pages. Also pretty much all the ads that are fixed to the pages are suggestive and sexual in nature, which to me isn't really acceptable on a comic book site, a place children could easily find themselves looking around and be exposed to inappropriate content. I opted out of targeted ads so I imagine they'll show up for anyone that visits the site. If it weren't for those things I'd have nothing bad to say about it really.
