Wings.io has ads to VERY malicious sites. One of them was arcadefrontier.com. Look that one up on mywot.com. Not cool. The Wings.io site itself is safe, with exception of the bad ads. I would highly recommend using an ad-blocker like Adblock Plus when visiting this site, or else just abstaining from it 100%. For child safety, people can name themselves anything, so there are lots of f-bombs. Again, to summarize, I don't see too many problems with the site itself, but it has bad ads and probably poor management since they let these ads get through. And, there is some pretty bad language. It is disturbing that people name themselves stuff like that. I'd recommend staying away. I can't say that enough. Use discretion when visiting.
