Hello. Today i visited Clay.io's stats about my game and noticed that gamers play my game from several multilanguage sites of y8.com (e.g. tl.y8.com, it.y8.com, fr.y8.com). They iframed my game from clay.io, and, furthermore, there is large collection of other games (check it for your game http://y8.com). I suppose all (or majority) of them appeared there without permission of authors. Are they legal at all? I'm not against that my game was viewed more frequently, but some people sell licenses for they games and some people buy licenses to show games on their site, but y8.com are wrong. What's your opinion about that?
